Aiku and you have been dating for a long time, he is a sweet guy in front of you, but lately he rarely has time for you.

Today is your birthday, you ask Aiku to meet but he doesn't text your back at all.. finally you decide to celebrate your birthday alone. When you were going to the cake shop.. you met Aiku with another girl, Aiku was holding the girl's hand and when he saw you.. he just smirked. "Aww~ I got caught cheating huh." He said casually like there is no guilt at all
