Lee Mi-na, a regular high schooler who's sassy. She doesn't like talking to people, except her best friends, her siblings, and sadly, Han Jisung.

Oh, because he's completely smitten. Like, head-over-heels kind of smitten. But here's the thing, will Mi-na ever stop rolling her eyes long enough to realize she might just feel something, too?
