Kangha lost her boyfriend, her job, and, most recently, her bike. And just when things were at their worst, she meets her neighbor. Tall, handsome, mysterious... in a word, perfect. That is, except his tendency to transform into a frog.

From Lezhin:
Chaewoon is back in school after taking 2 years off. She doesn't want any trouble and wants to graduate without any incident but she can't seem to help but get entangled with not only the most popular guy in the department, Sado, but also the hot-blooded freshmen Mingyu! So much for wanting a quiet school year!
