Best friend tutor for the first time and Chara college student

I went to school with my classmates. If you say something like a lover, you can join hands and return together. I want to shrink more distance, but I'm not sure how to move ahead... I think it's manly to kiss from me. No! AI is a serious child, so don't think about strange things! I seem to be busy with studying, but if I become alone, I will kiss the first time.
