Do Kyungsoo was never a social guy, to say at the least. 

Which is why recently during his lunch breaks, he'd take a five minute walk from his campus to the newly opened Café;

 because frankly, the library didn't do justice to its motto of keeping quiet.

He just wanted some time in solitude to read and study, he wasn't really into the trends or things of the sort.

And most certainly,  wouldn't take care to his surroundings unless they were bothering him. 

So Kyungsoo surprised himself when he became conscious of the girl he'd see in the back corner every day, sitting by herself and staring blankly as if she'd been looking at nothing at all.

...

But that was probably just because she was wearing a turtleneck in this ungodly hot weather.
