so I've already decided to write a little prologue in advance, here it is

An ordinary Monday morning, or so one should assume, but it is the first day after the autumn break. In the Asahina house, the hustle and bustle is going on, after all, it's school again today. Ema is sitting at the table with Wataru and Yusuke and is having breakfast. "I'm curious what the new student is like," says the red-haired man and bites into his bread. "Will she be like the other girls when she finds out that an idol is at the same school?" "You will see that later," said Ema simply and put away her things and then took her bag. One look over her shoulder and her brother was finished and stood behind her. Even if Ema doesn't show it, she's a bit nervous.

The girl crawled sleepily in her bed and looked at her alarm clock with still tired eyes. "SO MUCH" and she jumped up. She quickly dashed into the bathroom to get ready. "Man Sayu, couldn't you wake me? I don't want to be late on my first day!", The purple-haired girl complained at her sister. The person addressed was sitting at the table with a cup of coffee, looked up from her newspaper and just grinned. "Well it's your own fault if you stay up so long. I've already made your lunch ready for you, it's on the counter and your breakfast next to it." Already the younger one grabbed her food and opened the door. "Have fun at the university.", She called before the door slammed shut.

The school building was filled with loud chatter, after all, after the holidays, you always had a lot to talk about. Ema entered the classroom and immediately went to her seat. It was weird not having any of her middle school friends around. * I really hope that the new one is nice ... *, thought the brunette but was immediately interrupted by her brother. "Tell me, do you think it's bad if we still go to town after school? You always come out so rarely" The taller looked at her as if he had noticed her concerns. "I think it can be done," Ema grinned back.
At the door of her new classroom, Arisu took out her Coke bottle and took a long swig. It was funny to see the normally excited girl so nervous. * So go * And she opened the door. Everyone was so absorbed in their conversations that no one noticed the new girl, so she had time to look around first. As soon as she saw the face of a girl she knew, a smile stole onto her lips. She crept forward quietly so that she wouldn't be noticed.
Slowly the face of a girl pushed between the siblings. "O-ha-yo Chi-chan," said the girl. The eyes of the addressee grew bigger and bigger, while the boy just looked back and forth between the other two, confused. Ema so Chi-chan got up with such a swing that her chair rolled around and all eyes were now on her. With still wide eyes she looked at the other girl, who just grinned broadly back until they finally ran into each other's arms.Both laughed and had to be careful not to start crying. Now Yusuke looked even more confused. "Ai-chan what are you doing here", Ema asked when they had calmed down again. Ai sat on her best friend's table. "After I'm going to school here, what else?" She laughed. "But I thought you ..." "Yes, I know I'm back in Tokyo and I'm going to this class from today." She beamed. Ema had to laugh, yes, that's how she always knew her best friend happily and that's how she wanted to go to her brother. "Yusuke this is Arisu Kimura and Ai, this is Yusuke Asahina my brother." Now what it is about the Kimura to look confused. "Hello Arisu, nice to meet you.", The red-haired one began and held out his hand to the girl. Ai took this and shook it. "Likewise," she just mumbled. "I know it's a bit confusing, but after school we wanted to go to town. You can come with us if you want and we'll explain everything to you." finished the Asahina and his counterpart smiled and nodded in agreement.

so that's it for now, hope you enjoyed it a little
