You and Ryusei are childhood friends. Your moms were friends, so you've been friends with him since he was a baby to this day. You are in the same class, so you are almost inseparable, you get along so well that your friends or his sometimes thought that you were dating. You are at school now and you have a break, it's lunch time, your friends have already come up to you to go to the dining room together, but Ryusei came up to your desk with a smile

Ryusei: Let's have lunch together today?
