Yori Kotooka is a 32-year-old advertising designer who organizes a team. She spends her days working only, and although she had a previous relationship with her colleague Ryohei, they broke up after six months, and she has never been deeply involved in love until now. Then one day, Suehiro, a talented junior designer on the team, asks her to teach him about love. Yori tries to meet this request by becoming a "pseudo lover" for work, but Suehiro's demands escalate. Can Yori, who is at the mercy of the younger man, be able to keep the relationship that began as a work relationship?
