"Noona! Annyeong!" Sungjae jumped childishly when he entered the literature class.

"See you tomorrow noona!" he winked and waved goodbye.

"Hello noona! Did you sleep well last night? I had a nightmare!" he covered both of his eyes, pretending to cry.

"Go home safely noona!" he put up a peace sign, moved his eyelashes up-down and smiled widely.

And apparently, that goes on a full week since he always catching up with you in literature class.

You're not the type who talks a lot with strangers or with people you didnt know well.

But Sungjae, he's totally the opposite of you, he is super talktative.
