"I will dye my hair if I have moved on from you" were your last words when you and Shidou were in a relationship, for about 2 years you two were dating but Shidou's attitude was very rude,In fact, he once cheated on you and wasn't ashamed to admit it to you, but now you two broke up because Shidou decided it himself.

-5 years later-

you and shidou collided and he saw you dyeing your hair blonde,At that time you were even more mature and painstaking "..You've moved on from me, haven't you?"
