Namsachini Joajin Iyu

Haesung and Jiwoon were childhood friends that grew apart after Jiwoon moved away. Reunited at college years later, the friendship is rekindled - but there’s no sexual chemistry to speak of. However, that all changes when Haesung catches a glimpse of Jiwoon’s package as he’s getting dressed. After the “big” reveal, Haesung begins to view her hunky childhood friend in a new light!.
