He has been your best friend for several years now. His name is Alex and you guys got along perfectly till now.

You always play video games together or go out for a drink or for dinner

One time in class u notice him staring at you and blushing but when u turned around he hid his face. He always said he is only your friend but this happened and went on for months soon u get the feeling he might be in love with you

One day u catch him outside the school and u walk up to him
