Do you like Shinichi-nii?

　　Putting away his cell phone, Shinichi slowly walked upstairs.

　　Miku still stood stupidly in front of the door, her cheeks flushed, but she no longer showed an expression of embarrassment that made her want to cry.

　　Shinichi smiled, "...Miku, come back."

　　Walking towards her, Shinichi said with a smile.

　　"Shinichi, I..."

　　The voice that came out was as timid and soft as the cry of a small animal.

　　Miku looked like she wanted to say something, but Shinichi didn't give her the chance. As he passed her and entered the room, he whispered at a volume that only Miku could hear.

　　"...Wait and write ten more English questions. Next time I'll give you a hundred questions. Do you hear me?"

　　Pretending to be serious and with a slightly embarrassed expression.

　　 Miku relaxed her tense body and nodded vigorously.

　　"Um!"

　　Even though her heart was still beating very fast from embarrassment, when she looked at him, she no longer had the feeling of wanting to run away and hide.

　　 Miku returned to the room, hiding behind Shinichi, looking at the others a little worriedly.

　　Fumino said nothing, and continued writing with her head down.

　　Itsuki showed a relieved expression. She didn't ask any more, but she wasn't concentrating on her studies. Instead, she takes a notebook and tries to ask Fumino for advice, which makes her look embarrassed and keeps stealing glances at Shinichi.

　　Before Miku could smile, she and Rui met eyes.

　　Silence lasted for a while.

　　"…Sorry, I overreacted."

　　Rui remembers her uncomfortable expression when she left, he apologizes first.

　　Miku bowed, saying sincerely.

　　"No, the problem is clearly my fault. I was the one who overreacted. It has nothing to do with Rui. I am really, really sorry..."

　　"No, I clearly know you…" Rui turned her eyes away, her face reddened imperceptibly.

　　"You can't hold it in for a moment. It's natural to have such urges... Seeing how skilled you are, you should be with him more often..."

　　"Eh? Wait, wait, wait! What are you talking about?!"

　　Miku's face was completely red, and she was so panicked that she didn't dare look at Shinichi who pretended not to hear.

　　"No?" Rui tilted her head slightly, with a confused expression, "Even though it's a bit strange if you're not a couple, but if you have a good impression of each other, you should help each other or something. Like—"

　　"Stop, stop, stop!"

　　Miku rushed over and covered her mouth.

　　Not with her hands, but with her chest.

　　Miku rushed over and pressed Rui's face to her chest in panic

　　"I-I didn't do anything like that... It's still too early, and I was asked to take the initiative... Ugh, no..."

　　Even though she stuttered, some inappropriate scenes flashed through Miku's head and played themselves out without permission.

　　If there was no one else around, would she just go along with the mood, wearing black stockings and using her feet...

　　"Then... At least wait until everything that needs to be done is done before..."

　　The girl caught in the pink fantasy subconsciously hugged the pillow-like object tighter.

　　"Um... Save me...O...Ni-chan..."

　　As a result, the struggle in his chest grew weaker. After Rui twitched several times, she finally rolled her eyes and fainted.

　　Miku finally came to her senses, let go of Rui and said in panic.

　　"Sorry, are you okay…"

　　Shinichi who was watching the show on the side, quickly caught Rui's falling body.

　　"Come on, sit over there and write down the questions quickly! Don't touch my beloved little sister. If you can, target me—"

　　Fumino raised her head with a friendly smile: "Huh?"

　　"…Regarding the two beautiful girls next to me, you are not allowed to take action against the younger ones!"

　　Shinichi said solemnly.

　　Fumino glanced at her chest and sneered. After expressing all kinds of ridicule and self-mockery, she turned her sadness and anger into motivation and wrote like a devil.

　　Seeing them acting like this, Miku smiled slightly.

　　Itsuki stopped writing and looked up.

　　Feeling that the atmosphere that was originally tense was now starting to relax, then seeing Miku's expression which looked fine, Rui lay down in Shinichi's arms and peeked at Miku, Fumino's crazy study.

　　Everyone is a very good person.

　　△

　　Due to the emergency, break time was cancelled, and some people studied all afternoon, although their expressions looked tired, they also looked enthusiastic.

　　Soon it was afternoon, the setting sun outside the window filled the room and it was time for the girls to go back.

　　 Fumino was very upset at the moment.

　　Since there was no rest time, it meant she didn't have enough opportunities to verify whether Rui liked Shinichi as a man and a woman.

　　Even though they seem to show a jealous attitude towards Miku, siblings who have a deeper relationship shouldn't be able to bear it, right? This is by no means conclusive evidence.

　　After a day of studying, Fumino's mind was almost filled with formulas. Now she couldn't think of any solution, and she was too embarrassed to stay any longer. She gave up the temptation for a while. If there was a chance she would make more plans later.

　　Unexpectedly, when Miku and Itsuki left with Rui's handmade biscuits as a gift, Rui took her hand and ran into the kitchen.

　　Fumino was confused, but Rui got straight to the point.

　　"Furuhashi Senpai, it's a bit impolite to ask this suddenly. Do you like Shinichi-nii?"

　　Fumino: "😐"
