Otona no Koi wa Bukiyou na no de

He's a decent worker, single and comfortable, and hasn't had a romantic relationship for years. One day, Ukigaya, who is enjoying a peaceful life in his 40s, meets a handsome, elite man named Shindo. He doesn't get along with Shindo in many ways, and he always looks down on him, gets angry at him, and makes him feel like he's being pushed around... Ukigaya, who used to be a bitch who ate all the straight men, thinks to himself that "I might have had my eye on Shindo in the past," when he sees how good-looking he is, but laughs at himself for thinking it's ridiculous. But one day, he finds out Shindo's "certain secret," and their relationship changes... A love story of an age gap between a young, sharp-tongued elite and a former bitch!
