Umi Nakano

Umi Nakano (中野 海, Nakano Umi) is a supporting character in Rent-a-Girlfriend (Kanojo, Okarishimasu).

He is a handsome, popular friend and classmate of Chizuru Ichinose (Mizuhara) from their acting school/theater circle. Umi is an aspiring actor himself and has a significant social media following. He has romantic feelings for Chizuru and has confessed to her (though rejected), which often makes him a source of jealousy and insecurity for the protagonist Kazuya Kinoshita, who initially mistakes him for her real boyfriend.

He's generally portrayed as kind, supportive (e.g., helping Chizuru with her career), and sincere in his affection, but remains a rival-like figure in the story's romantic dynamics.
