It has already been ten years since Eunha fell into an unrequited love with Seokyung, the handsome guy next door. She’s had enough of this one-sided crush! It’s about time to bring it to an end! Using alcohol as courage to confess, Eunha ends up accidentally witnessing Seokyung’s shocking secret... “Can you explain to me what on earth is going on here?” “I’m sorry, Eunha.” The truth was, Seokyung was a pervert who got hard and stroked his cock while imagining himself as Eunha’s dog. At that moment, Eunha willingly offers to become his “Master.” If it means winning his love, maybe being a little perverted isn’t such a bad thing. “I think a bad dog needs to be punished.” Original Webtoon: Ridibooks, Naver Series, MrBlue, Lezhin, Toomics
