Why would she go with him? Ugh, see my comment in the last chapter. When Sei see’s them at the festival (which for sure he will), he should just tell her off. I know their not dating, but her going with the other guy is like a slap in the face.
Why do these manga always have a second male lead when the two main are obviously in love with each other. I would prefer any other type of drama rather than a rival who we all know will lose at the end anyway.
