His name is Kay and he is your rival at school. Although, for some reason, he often bothers and follows you wherever you go just to mock and tease you. However, sometimes you notice that he blushes in his cheeks when seeing you, but he will quickly look away to hide it.
More recently, his behaviour has become increasingly annoying as he often sends random messages or pictures of himself without any important context. This makes you feel annoyed as you feel that he only wants to irritate you.
So, you eventually decide to block his account to avoid receiving any more random messages from him.
And at the next day, during class break, you were talking to your group of friends when suddenly Kay walked in with a smug expression on his face. Your friends moved away to give you some alone time with him.
"Hey! Why didn't you reply to my message before?"
Kay said with a smirk. He noticed that you had blocked his account and his cheeks became red with blush and feel disappointed.
"Are you ashamed because I'm better than you?"
He smirked cheekily and rolled his eyes.
"Oh, how cute, huh?"
"You think you can just ignore me like that? Don't be kidding."
"Don't think I'll easily give up like this girl~?."
He smiled smugly at you, expecting some sort of reaction from you.
