S + S = ? ? ?

"It hurts! You bastard!" Kawaki cursed as he got up.

Seeing that the two of them were going to start fighting over some trivial matters, Shinpachi quickly stood between Kawaki and Gintoki.

"You guys should stop before you go too far," Shinpachi was a little helpless, "Speaking of which, why do the two of you fight each other whenever you meet? You should get along with each other occasionally."

"Of course, it's not good to see him!" Gintoki and Kawaki roared at the same time.

"You two, be quiet!" Shinpachi shouted, "You obviously know that Miss Mitsuba can't be irritated, but you can still make such a fuss! You should also consider others!"

"Tsk!" Gintoki and Kawaki turned their faces at the same time and snorted disdainfully.

...

Edo Harbor.

"Deputy Chief, look, those people are starting to move!" Yamazaki looked at the people coming down from the ship with a binocular and reminded Toshiro in a low voice.

"Ah, I know," Toshiro said, "Follow them closely. We have to figure out their true identity tonight!"

"Yes!"

...

In front of a certain magnificent residence.

"Is this home of your sister's fiancé?" Kawaki said to Sogo, "It's really incredible."

"It's exactly the feeling of being a rich man," Shinpachi said with a sigh.

"Gin-chan, little uncle, can I marry someone like this in the future-aru?" Kagura asked with a face full of anticipation.

"That seems to be a little difficult..." Kawaki smiled awkwardly.

"Don't talk nonsense!" Gintoki retorted, "That is not a little difficult at all, but there is no possibility at all!"

"What did you say?!" Kagura instantly exploded and punched Gintoki in the stomach.

"Ah!" Gintoki clutched his stomach in pain, "What the hell are you doing? You stinking girl!"

"It doesn't matter if I can't get married." Kagura instantly switched to the posture of a little girl and said squeamishly, "I want to stay in Yorozuya forever with everyone."

"At first glance, it sounds like some touching lines. But when you think about it carefully, it doesn't seem to be the case!" Kawaki said expressionlessly, "Gintoki, it's really hard for you."

"It's good that you understand," Gintoki sighed softly. Then, he extended a finger and suggested, "Since you know, then the future alimony..."

"Die," Kawaki said with a smile.

"What do you mean by die?" Gintoki scolded, "At least you should have a bit of shame! Don't you want to pay a little child support for your niece in someone else's house?!"

Just as the two of them were about to fight again, Mitsuba, who was standing in front of the house, covered her mouth and laughed. Gintoki and Kawaki also stopped.

"So-chan, your friend is really interesting," Mitsuba said with a smile, "Thank you so much today. Big Sis had a great time."

"Why don't you just come to the station to sleep today? Even if it's the home of your fiancé..." Sogo handed the gift bags in his hand to Mitsuba and asked doubtfully, "After all, you are not married yet. Isn't it a little inappropriate?"

"Sorry, there are many things to do here." Mitsuba smiled apologetically and then looked at Kawaki and Yorozuya trio, "Kawaki-san, Sakata-san, Shinpachi-kun, and Kagura-chan, thank you very much today."

Kawaki crossed his arms and nodded with a smile as a response.

"Don't worry about it." Gintoki shrugged with a face full of disapproval.

"It should be us. We had a lot of fun with Miss Mitsuba today." Shinpachi bowed and said. He could be considered the most polite of them all.

"Big Sis S! You must do your best!" Kagura gave her a thumbs-up, full of energy.

"Ara, I got it." Mitsuba could not help but cover her mouth and laugh again.

"Then, sister, we will go first. You should go in quickly." Sogo cared, "After playing for half a day, you should be tired, right? It is better to have a good rest."

Mitsuba responded with a smile. She turned around and raised her hand to push open the door of the house, but just after he raised her hand, she stopped. Then, Mitsuba's voice sounded again.

"So-chan, that... that person..." Mitsuba turned around and hesitated.

"I won't let you meet that bastard," Sogo replied without hesitation and then turned around, "He went out to work without saying anything this morning. What a heartless bastard..."

After saying that, Sogo lowered his head and left.

Mitsuba looked straight at Sogo, who was walking further and further under the dim yellow street lights, and the emotions in her eyes seemed to be a little low.

"Work, he really hasn't changed." The corners of Mitsuba's mouth slightly raised.

"Really. You casually dragged others into the water and then walked away alone." Gintoki spat in disdain.

"Can you be a little bit more self-conscious?" Kawaki scoffed expressionlessly, "It was clearly you who jumped into the water, okay?"

As he spoke, Kawaki looked at Mitsuba and smiled, "Then, it's time for us to leave."

"Ah, thank you so much for today." Mitsuba replied, "Also, please forgive my So-chan in the future."

"Don't worry about it. Sogo-kun has always been a good child." Kawaki hurriedly replied.

"Your level of nonsense is too low..." Gintoki casually retorted, "Good child? Where did you see it?"

"Take a look at the atmosphere!" Kawaki retorted in a low voice, "At a time like this, you should talk more about Sogo-kun's merits so that Sogo-kun's sister can feel at ease!"

Hearing this, Mitsuba could not help but laugh again. Then, she covered her mouth and said with a hint of apology, "I'm really sorry. So-chan has always been a willful child. All of this is my fault. When he was young, our parents passed away. In order to not let the child feel lonely, I spoiled him a little too much."

"He is willful, stubborn, and hates to admit defeat. Because of this, he has been alone since the beginning. He doesn't even have a friend." Speaking of this, Mitsuba showed a trace of emotion on her face, "If he didn't meet Kondo-san, what would he be like now? I'm still very scared to this day. Has the child turned bad..."

"Has he become bad?" Gintoki scratched his head and casually replied, "Of course. He is lazy at work, a super S, often doing some bad things, and a super S. That damn brat... Ah!"

Before Gintoki could finish his sentence, he was thrown over by Kawaki.

"There's nothing at all," Kawaki waved his hand and smiled, "With a sister as gentle as you, Sogo-kun will definitely become a good child."

"Even if Kawaki-san praises me so much, you won't get any rewards from me." Mitsuba covered her mouth and laughed, "Also, you are not So-chan's friends, right? I know..."

Before Mitsuba could finish speaking, he was interrupted by Kawaki, "No, we are friends." As he spoke, Kawaki took out his phone from his bosom, "Look, we often send messages to each other~."

[I successfully sent Hijikata flying today~ Boss, your method is really useful. Attachment jpg.] The attached picture was Sogo, who was holding a bazooka, and behind Sogo was Toshiro, who had already been blown unconscious.

[The poison from yesterday night is very useful. Hijikata-san stayed in the toilet all day today. Attachment jpg.] The attached picture was Toshiro, who just came out of the toilet with a pale face and a hollowed-out body.

[According to the boss' suggestion, I hid all of Hijikata's mayonnaise today. It's really interesting to see him looking for mayonnaise with a face full of displeasure. Oh, right, this is Hijikata's unhappy appearance. Attachment jpg.]

...

"What are you two discussing every day?" Looking at the messages on Kawaki's mobile phone, Shinpachi's face was full of black lines, and the corners of his eyes twitched as he said, "It seems that you are partly responsible for Okita-san becoming like this today..."

"What?" Kawaki was puzzled.

"Don't play dumb! You're also an S!" Shinpachi scolded.

"So, it's better to keep that stinky bastard away from this guy," Gintoki spread his hands and muttered, "When S and S are put together, there will be a reaction. Moreover, it will be an incredible reaction. The earth might explode because of this..."

However, just as he finished speaking, Gintoki found that Mitsuba's gaze was still on Kawaki's mobile phone screen. On the screen was... Toshiro.

"To... shiro..." Mitsuba unconsciously murmured.

"Toshiro? Who?" Kawaki asked doubtfully.

"Ah!" Seemingly aware of her own situation, Mitsuba hurriedly waved her hand and said, "Nothing, nothing. I was just spouting nonsense just now..."

However, at this moment, a beam of light came straight at them. Then, everyone heard the sound of a car engine.

Everyone was curious and forgot about it. Mitsuba also turned around and forgot about it.

After a while, a Shinsengumi police car stopped in front of everyone. Toshiro got out of the car and glanced at the house at the side, "Hey, what are you doing here? This mansion is..."

When Toshiro slowly moved his gaze to Mitsuba, his pupils suddenly shrank, and his voice stopped abruptly. The cigarette in his mouth also fell down.

"To... shiro-sa..." Mitsuba covered her chest and muttered, but she began to cough violently as soon as she finished speaking.

"Hey! Are you alright?" Kawaki hurriedly took a step forward. Gintoki, Shinpachi, and Kagura also quickly stepped forward.

Before Kawaki could come to Mitsuba's side, Mitsuba had already slowly fallen to the ground.

"Hey! Are you alright!" Kawaki shouted, and then he was about to help Mitsuba up.

However, at this moment, Toshiro took the lead and rushed to Mitsuba's side. He helped her up, but then he stuffed her into Kagura's arms, "You are a girl. Help her."

After doing all this, Toshiro stood up and looked at Kawaki with a gloomy face. He muttered, "Don't touch her with your dirty hands!"

Kawaki: What? What? What?
