"The thing Shim Cheong-ri regrets most is the one-night stand with the man she'd had a crush on for eight years—and taking money from him afterward. Since then, Go Hyeong acts cold and distant by day, as if she's a stranger, yet by night he clings to her relentlessly, trying to get her back into his bed. When Hyeong's arranged marriage is finalized, Cheong-ri draws a line with him—but despite the breakup, she's dragged to the man's house. Because of a grudge from the past, Gyeongseong's Go family collapses overnight. The scarred man lets Cheong-ri go, yet keeps appearing to save her from danger. Cheong-ri thought she was just a plaything he could do without, but unexpectedly, Go Hyeong was deeply in love with her all along."
