🏆 Why Sexual Relationship Development Ranks at the Top
Back in high school, Seong Jihyun had a bitter history with Baek Ian — a rivalry twisted out of shape by Ian’s obsessive need to always beat her. Jihyun expected never to see him again after graduation. But now, reunited as adults, Ian approaches her in a completely different way… and his old competitiveness seems to have turned into something far more intense, dark, and possessive.
