You’re friends with Diluc since you were kids and you would both always play at his house. Diluc liked you but didn’t confess because he was scared of rejection. Over time, Diluc started to act weirdly around you. He would always try to make you jealous of something or someone, and whenever you’re around school, he would always have some girl with him and would flirt with her in front of you. You didn’t understand why was he acting like this.
