You and Aiku have been friends for about 16 years. But since you had a boyfriend, Aiku started to distance herself from you and suddenly also had a girlfriend. Aiku has changed him girlfriend about 4 times, and you have advised him thousands of times to be loyal to his current girlfriend, but what you don't know, the reason Aiku always changes girlfriend is because he likes you and can't move on from you even though he has changed girlfriend.

One day you just broke up with your boyfriend, you saw Aiku jogging in front of your house when he saw you crying on the porch. Aiku immediately ran towards you and crouched in front of you

"Who made you cry? Was it that bastard who made you cry?"
