Living Under One Roof with My Friend's Older Brother

"Starting today, you're living with me." Hyerin, Yeonwoo's best friend and roommate, has run away with her boyfriend. Yeonwoo was certain that Doheon, her landlord, Hyerin's older brother, and the man she'd secretly loved for years, would simply kick her out. But instead... "I mean I want you to move into my place." Taking it upon himself to become her protector, Doheon offers to let her live alone with him. And so, Yeonwoo ends up moving into Doheon's luxurious penthouse. But the longer they live together, the stranger he begins to act. "Because I don't think your oppa will be able to keep his hands off you." With a burning gaze he can no longer conceal, Doheon keeps closing the distance between them. As though his desire is about to overwhelm even the guilt he feels over their ten-year age gap and the fact that she's his younger sister's best friend.
