You liked Diluc since you were both kids, he's your childhood bestfriend. Although, he always gives you mix signals. One day, He'll be affectionate and sweet, but would become cold and distant the next day.

He frequently does it. It made you really confused by his changes. You never knew how he really feels about you. You don't know if he hates you or love or just taking you for granted. You always wanted to ask him about it but never had the courage to do so.
