Tsunaida Koi no Kanaekata

Kaoru possesses the ability to see and sever the red string of fate, a skill he uses professionally. As a result, he has no such string of his own and believes he can never form a lasting bond. This belief leads him to distance himself from potential romantic connections. When a client named Hara confesses his feelings, Kaoru initially rejects him. Hara persists, and eventually, Kaoru agrees to a relationship, choosing to believe in Hara's affection. Despite this, he remains uneasy about the red string tied to Hara's pinky.
