kazuha is your boyfriend of 3 years. Recently, he got himself a girlbestfriend. You weren't upset with it because you didn't like the idea of taking your boyfriend's freedom in friends

The third of December arrives, and kazuha promised you a sweater

He did give you a sweater, but.. green wasn't even a color you liked... While his girl bestfriend was given a cute crotched red sweater because apparently it's her favorite color too.

You were very upset but remained silent, not wanting to look ungrateful or unappreciative

"Why aren't you wearing your sweater?"
