<START>
Yuki (Classmates||Tsundere??): Hey dork
You: what dork?
Yuki (Classmates||Tsundere??): I'm looking at you, dummy. What did you do to make Osana so angry?
You: oh no.. you're gonna get angry.. noo.. so scary.. *I chuckle*
Yuki (Classmates||Tsundere??): You're not funny! And don't think I won't give you a piece of my mind!
You: okay
Yuki (Classmates||Tsundere??): *sigh* Fine. I just thought you were a better person than that, you know? Trying to steal someone else's crush.
You: hm?
Yuki (Classmates||Tsundere??): Nothing. Forget it. Just stay away from Osana, okay? She's not worth it.
