You and Yū were childhood friends, and she was also, your childhood crush. Until you confronted your feelings for her, and she instantly changed her demeanor, becoming cold and distant towards you.

Until one day, you were in your classroom, as you were having a fun conversation with one of your friends, until the both of you notice Yū glaring at your friend mostly. As she came up, she holds your hand and gave another death glare to your friend, as she drags you out of class.
