Maybe there is still a long way to go before reaching adulthood

　　Nakano Family.

　　His bag was placed on the chair, and Shinichi sat on the pillow next to the bed.

　　Actually, being in the same room as beautiful quintuplets is not a pleasant experience.

　　At least that's what Shinichi thought.

　　"The lines here... Um, this expression would be better? A little angrier?"

　　While holding the script, Ichika changed her expression several times, she suddenly remembered something and smiled.

　　"Shinichi-kun, can you look at this part for me? I don't understand it."

　　She patted the empty space beside her, her eyes filled with hope.

　　Shinichi stood up as instructed and was about to leave when Nino, who was in the middle, looked away from the phone, glanced at her, and spoke to.

　　"Don't step on me or touch me. If you can't, don't go there. You can teach here."

　　Her legs were spread apart, and the legs beneath her sport shorts were straddling him halfway. She swung a leg painted in pink nail polish, making it clear that "if you have the balls, just step on them and see.

　　Shinichi looked at her feet. But after hesitating, so as not to disturb Miku's rest, he finally decided to ignore the mistake and proceed carefully, without even looking at her.

　　Who knows what made Nino angry, ever since she came back from the zoo, her attitude had changed, as if she had returned to the time when she was still seeking revenge against him.

　　Shinichi didn't mean to understand the girl's mood in a confused state.

　　So before understanding the basic situation, he decided to pretend not to see Nino's attitude towards him, so as not to make her feel worse.

　　"Thank you Shinichi-kun, thank you for the long journey."

　　Ichika glanced at Nino and smiled for some reason.

　　"Tsk"

　　Nino rolled her eyes to look at her.

　　As their eyes collided, invisible sparks crisscrossed the air, igniting the faint smell of gunpowder smoke.

　　Yotsuba trembled on the side.

　　"Itsuki, I want to get out of here..."

　　Itsuki looked up doubtfully.

　　"Eh? Have you finished this matter?"

　　"Not yet... But at least change the place..."

　　"Don't be afraid of the heat. The heat will cool down naturally when your mind is calm."

　　Itsuki smiled, but Yotsuba crossed her arms and trembled.

　　"You misunderstood, it's not actually a question of whether it's hot or not..."

　　"Okay, don't worry. I'll go down and get some ice later. Now just concentrate on reading. I've thought of a solution that might work for you. See if you can write it down…"

　　"Uuuuuuu.... Itsuki is more than just a mother than a mother..."

　　Yotsuba was almost crying without tears, being pulled into the study room by Itsuki who looked quite happy

In the summer heat of August, six people are huddled in the same room without air conditioning, and four of them have a complex polygonal relationship. This makes Yotsuba sit in a tight spot, always distracted from observing the interactions between them, and she feels out of place and embarrassed.

　　As for Itsuki, at first she studied in her room, but for reasons "Asada-kun, a male high school student, couldn't be left alone in Miku's room. I will watch over her"

She openly put down the reading equipment and she brought a folding table and read here with Yotsuba who didn't have time to escape.

　　So, the electric fan blew the girls' hair in the corner, but the stuffiness in the room didn't decrease by half, leaving Miku lying on the bed...

　　Not daring to say a word, she hid quietly in bed, pretending to be asleep to cover her already red face.

　　After all, what the two of them said not long ago was known to the four people who were eavesdropping outside the door.

　　Including wanting Shinichi to stay, changing it date home, whether she wants to do perverted things, etc., it all sounds...

　　When Shinichi noticed there were four pairs of eyes staring at the door, both of them were almost like middle school students who had been caught dating secretly. They let go of each other's hands, one sat back against the pillow and the other shrank in the blanket and acted like a coward.

　　After that, they had no room to be alone at all, as if they were afraid that Miku's life would be in danger.

　　The sisters don't say much now, but Miku knows in her heart that after Shinichi returns, she will be severely criticized by Nino and Itsuki for being shameless.

　　She was clearly the most calm, simple and passive person in her family, yet she dared to say such seductive words to the boy she liked right in her room.

　　△

　　When Miku fully woke up, it was already evening.

　　The sun has set.

　　"Did I just fall asleep like this…"

　　She rubbed her eyes sleepily and looked around.

　　Even though her body was still as weak as before, the discomfort had almost subsided.

　　"Even though I woke up to eat halfway, I don't seem to remember it."

　　Itsuki pressed the back of her hand to her forehead, and poured her a glass of warm water.

　　Miku took it and moistened her throat. She was almost awake at this time. she looked around at the empty room again and couldn't help but wonder.

　　"Where is everyone?"

　　"This is an unfortunate time for you to wake up. Asada-kun is back. Ichika and the others will see him off." Itsuki pressed her shoulder and warned her.

　　"You can't move when you're just healing. You should get enough rest first, and then send him a message when you feel better."

　　"Okay..." Miku slowly lay back down on the bed without resisting Itsuki's urges.

　　"I just think it's a shame that a first date ended like this..."

　　Itsuki blushed, and lowered her head in shame.

　　"I am really, really sorry. Following you and not leaving you alone..."

　　Miku saw her sincere apology, and she spoke softly.

　　"Actually, it's nothing. After all, it was impossible for me to truly have contact with Shinichi. It would be easier if you were here…"

　　She sighed, and muttered in frustration.

　　"It's kind of hard for me to have two people alone in a room... I don't think I'm mentally ready."

　　If anything, she could stop relying on momentary impulses….

　　Even if she don't have a fever, it's not impossible to take the initiative...

　　"Miku?"

　　Itsuki looked at her in surprise, then deliberately coughed, and her eyes slowly wandered.

　　Even though there was no one else, she still looked around guiltily. With uncontrollable shyness and curiosity, she whispered into Miku's ear.

　　"Okay, Miku, if you're embarrassed to answer, it's okay to ignore me..."

　　"If we weren't home at that time, Asada-kun turned into a wild animal, jumping on the bed and saying what he wanted to do..."

　　"Are you really going to do something like that with him?"

　　"?!"

　　Miku's eyes widened, her face red from her neck to her ears, and almost hid under the blanket again.

　　"Is it true? Or not?"

　　Itsuki gulped, and was nervous, but her eyes were filled with a strong desire for knowledge.

　　Now that she had asked all the questions, she looked at her without flinching. Itsuki was eagerly awaiting her answer right now, looking at her very seriously and she wouldn't let it go.

　　Miku hesitated for a moment, then loosened and tightened her hands on the blanket.

　　But for some reason, she suddenly laughed, and spoke to Itsuki.

　　"Maybe, maybe not? Besides, I'm a patient now, and I can't stop Shinichi from doing whatever he wants to do."

　　Itsuki was clearly dissatisfied with the answer and continued asking.

　　"I've read in a manga before that the originally gentle protagonist was drunk and was about to defile the heroine, but was awakened by her tears. So if it was Miku, Shinichi-kun should be able to…"

　　Miku interrupted, and this new experience made her laugh even happier.

　　"Perhaps, you seem to be very interested in this kind of thing. Is it possible..."

　　"I!?"

　　Itsuki's eyes widened in surprise, then she quickly packed up the information on the folding table secretly, but her face was already redder than a tomato.

　　"I'm not... That... This is just casual curiosity about sexual relations, and this is academic psychological research! Miku, please don't change the topic!"

　　"Hah, if you admit it, admit it, otherwise I will rest. I'm tired."

　　Miku slowly shrunk into the blanket, looking at her with only a pair of sly eyes.

　　"Uh~~" Itsuki's eyes filled with tears, she covered her face in shame and frustration.

　　"Forget it, I won't ask again...

　　"Miku, why do I feel like you're becoming like Ichika and starting to like teasing other people..."

　　Miku smiled and shook her head, imitating Ichika's mature tone.

　　"No, I think Itsuki is very cute~"

　　"Why so..."
