the plot is basically enemies to lovers. i can remember that pcy was a basketball capt, and baek is i think part of choir... anyway, they always fight over the gym or smth. they were also titled as "that one pair who will never end up together" or smth in between in their graduation. years passed, they both attended their batch reunion with a baby! that surprised everyone too.

i tried my best but that was what i can only remember... :(
