Dekiai Secret Lover

Nagato Momiji dislikes his fellow actor Akira Shinonome. When they last performed together, Shinonome called Momiji by “Momi-chan,” and that gave people a cutesy image of him that stuck. When he really wanted to present himself as a cool dude! Despite that, he and Shinonome got the chance to co-star in a drama, and they had a get-together to celebrate. Drunkenly, Shinonome's usual kind smile disappears, and his Kansai accent becomes a little slurred… Suddenly, he kisses Momiji and confesses, “I've always had a crush on you...”!
