Fed up with his "women troubles," Naoyuki's parents send him to live with his uncle, Yagi Akira, whose sexuality is rather ambiguous. At the apartment complex, Naoyuki meets Yoshiro Kei, another one of the tenants and he can't help but be curious about Kei.
Love is Blind...it's also bloodthirsty and has one hell of a sense of humor. Sa Rang and Jung Yul are identical twin sisters who couldn't be more different. One is sweet and introspective, while the other is a manipulative harpy. Nan Soo and Yoo Shin are best friends who aren't that much alike either. One is a hot-headed jock while the other is an intelligent pessimist. When love comes to town, the lives of these four teens are turned upside down when rotating attractions, comedic misunderstandings, and general chaos force them to reconsider everything they've ever known about relationships, trust, and the frailties of the human heart. Fortunately, none of them knew very much in the first place.
