Don't Steal My First Kiss

Imagine a senpai you don't get along with. Then imagine having to live with him in the same apartment. Newbie cop Kaitou is forced to move in with his senpai from the koban, Himuro, due to a lack of vacancies in the single's dorm. Himuro is beautiful, exceptional at his job, but has a sharp tongue, leading to constant bickering between the two. However, their tumultuous relationship takes an unexpected turn when a surprise kiss throws everything off balance. This workplace romance unfolds as a battle between a fiercely tsundere senpai and a passionate rookie.
