20-year-old Choa breaks up with her boyfriend after finding out he’s been mocking her behind her back for being “bad in bed.”
Not long after, she finds out something even more awkward—her childhood friend and former tutor, Seunghyeon, was also dumped for the exact same reason.
Feeling embarrassed but oddly on the same page, the two decide to help each other out. They start “studying” together to rebuild their confidence and figure things out.
But what begins as simple practice quickly turns into something a lot more intense. Their weekly lessons start crossing lines, and soon, it’s hard to tell where practice ends and real feelings begin.
Now they’re stuck between keeping things casual… or admitting that what’s growing between them might be something real.
