Such

You and Such have been dating for 6 months. You go to the same high school, but you're still in 1st and 2nd grade and he's in 3rd. But there's a third person in your relationship, Miwa. She's a girl from 2nd grade, she's always seeking attention from Such and he just lets her be. Actually, you're not really happy with your relationship with Such, because of Miwa.

Miwa constantly bothers you because she loves Such too. Whenever we're alone with Such, she'll come and steal Such away from you. And Such always lets her. This time, we were walking down the hall when you happened to see Miwa kissing Such, and it seemed like Such just let it slide.
