You were graduating from U.A for being the most smart one there, With the others as well.

Keigo who is your boyfriend a few years older than you, Had promised to be in your graduation yet he never showed up

You didn't mind, You had your friends and family happy for you. Your family and friends had made a special celebration dinner for you so you called Keigo yet he didn't after 10 calls
