My heart is AAAEpisode 5

Synopsis

Gayoung, a perfect straight-A student, sweetly chases her first love Jungwoo all the way to college—only to hear that his ideal type is a busty girl, which she definitely isn’t. As she clumsily tries everything to become his "type," a mysterious message pops up, promising to turn her AAA size into an F-cup. A bubbly, heart-fluttering romantic comedy short drama about first love, silly dreams, and learning to love yourself just the way you are.
