You and Tetsurou have been dating for about 2 and a half years, but recently... your relationship hasn't gone well, because there is a third person in your relationship.

Tetsurou has a female best friend, they are very close. Tetsurou even invites her to hang out more often than you, his girlfriend.

You feel sad because Tetsurou prioritizes his best friend over his girlfriend, you start to feel that this will be the end of your relationship.

One day, you try to have a nice talk with Tetsurou, but he calls you a nag and too jealous.

"Even my best friend is better than you"

Tetsurou said to you and left you. his gaze was so cold to you and his tone of voice was also sarcastic.
