What Is This Sh*t?'s Manga

As the other person said, it has BIG POTENTIAL.

At first you'll easily get ticked off at how MC won't break up with his bf (actually I still am annoyed about that) but I think when It starts to get to those chapters where the phone with love thing (love meter? I didn't really understand half of the things it said on the manhwa but I just guessed it's a love meter bar or a jellypop that can know how many people love or loved you?) gets explained. Also this plot is just saving us with the hot dudes popping up left and right.

We'll see who the endgame is maybe I'll be 60 yrs old before then.

Edit: Why tf is missy worrying about dying alone when she's still in highschool
Girl stop worrying about that sh*t and live your life! Cause who knows maybe you won't get to do the good sh*t you want even when you have a partner. (I'm saying all this sh*t then when I get older I don't have any partner in life LMAO) Also translation still kinda wacky but maybe it'll get better unless it deteriorates...
