Wedding planner Itsuki makes her living by helping the relationships of others. Her own love life, however, exists only on dating apps, and can only be described as a complete failure. Dumped by ten men in a row, her daily routine consists of venting about her failures to her childhood friend, Tomo. Though they often butt heads, Tomo is a constant source of comfort for Itsuki. One night, however, a drunken bout of joking around leads to an unexpected kiss! Itsuki's body can't help but react to Tomo's soft lips and warm fingertips. "Just let me do you". When his eyes full of masculine desires meet Itsuki's, all resistance melts away, along with the possibility of remaining friends. Tomo was the last guy she thought she'd ever consider, so is it really okay to be having sex with him?!
