Warning: fluffs everywheereee, bottom!jongin(is that even a warning?)

This prompt is from a sekai fanart i saw few days ago!

I've never write stories before but after I read a lot of fanfics and it gives me an inspirational to write one myself. 

English is not my first language so please excuse my grammar error.

Please enjoy and leave a nice comment ｡^‿^｡
