A Pisces in Leo

kim yerim is a sophomore in high school who won't spend any of her days without talking about horoscopes.

her belief has been growing ever since she has the horoscope prediction application in her phone that would give her predictions about every aspect of life.

one day, the application suddenly launched a new feature called compatibility prediction. it tells her that the pisces zodiac ㅡ which is hers ㅡ is least compatible with leo.

she becomes so curious to prove whether it's true or not, but the only way to prove this prediction is to date a guy who is a leo guy ㅡ or at least befriend him.

and the only guy whom she knows has that zodiac is mark lee.
