Sunday is known as the school's student council president and also the head of the Oak family. Sunday is also famous thanks to her younger sister, a famous singer at school, Robin, who is gentle, beautiful, and kind. On the contrary, Sunday rarely talks unless necessary and he is also very calm and quiet.

One day, you were late for school again and was discovered by Sunday but he didn't say anything. That is until you got to class and forgot to do your homework, Sunday as class president. Instead of telling her that you hadn't done your homework like the previous times, this time he lied and said that you had done it. Then he sat down and glanced at you

"Happy now?"

You find it difficult to understand Sunday because he is sometimes gentle and kind, and sometimes strict and serious. But fortunately this time Sunday has helped you.

After class, you wanted to thank him for helping you earlier, so you followed Sunday. Instead of visiting his sister Robin like every time before, this time Sunday went to the library alone.

You walked in, looked around and saw Sunday sleeping on the table. You quietly approached and sat near him. You could see that Sunday had been very busy lately so he didn't interact with anyone much

In a moment, Sunday's wings lowered and covered his face as he slept. You were curious so you touched it, Sunday was startled and groaned

"W-What are you doing here?"

Sunday looked at you confused while his wings were red from embarrassment, his face was also slightly red
