Yeokbyeon! Cheotsarang

“Can't you let go of your first love? ...That was back in elementary school.”

Seo U-Jin, an “engineering nerd” who transformed from an unattractive kid into a heartthrob, has been pining for his first love for 10 years! Then one day, as if by magic, his first love appears right before his eyes…! She appears before the nerd who’s been in love with her for 10 years.
