Sone-san's Pure Love Proposal: Steamy Persuasion from a Man with a Psychopath's Face

Synopsis

Kanako Akiyama, an office worker, has been in a physical relationship with her college crush, Yuki Sone, even after graduation. Despite his clear boundary of "no dating," she finds herself unable to resist him whenever he calls. One day, a turning point arrives when a younger male colleague makes a serious move on her, finally promising to move her stagnant life forward. However, that night, Sone—who had let himself into her room with a spare key—discovers everything from her phone. The intense possessiveness and jealousy of this "handsome psychopath" senior, hidden behind his usual cool demeanor, finally bare their fangs. "I'll make you spit out everything about that other man." Driven mad by jealousy, Sone interrogates Kanako, exposing every inch of her heart and body to make her his alone. Just when she thinks he's taken everything, she remembers him once whispering, "Want to get married?" Tossing and turning under his erratic behavior, Kanako finally confesses her long-held secret: "I've never had a boyfriend because you were always there, Sone-san." Where will this tangled, unrequited love lead? A pure yet twisted story of a serious marriage persuasion.
