Interest rate 50% summary: Rookie director Lee Seorim has been plagued with headaches lately. Ever since top star and most popular actor these days, Lee Seonoh, was cast in Seorim’s project, he hasn’t been participating in the production at all.

But Seorim has one last trump card: the so-called “I know what you did last winter!” Seorim had once met Seonoh by chance in the past and knows something about his secretive history. Planning to use that knowledge to blackmail him, Seorim instead gets an utterly absurd response from Seonoh... “So, when are you going to take my virginity?” Original Novel: RIDI, Bomtoon, MrBlue, Bookcube Original Webtoon: R19: Ridibooks R15: Ridibooks
