Kawaii Hito.

Takane Chihiro, a man with style and looks that could kill, unexpectedly reunites with Kenichi Sakuya, his ex-wife's younger brother. Kenichi is shy, reclusive, and easily frightened. When Chihiro is asked to look after him, he finds himself unable to refuse, despite normally avoiding such responsibilities. For the first time, he must learn to handle a fragile fledgling like Kenichi.

Meanwhile, after the trauma of being betrayed by a childhood friend, Haru Tsumura became a recluse. One day, he gets injured during a fight and collapses on the street. He is picked up by Eiji Kagami, a man who might be able to change Haru's heart. As their paths cross, both pairs must navigate the delicate process of opening up to others and finding connection.
