Title: The Man Who Shattered My World
Tachibana is a player, and he's exclusively a top. He has no intention of falling in love or maintaining a romantic relationship, and to ensure his partners are aware of the status quo, he has them agree to a relationship contract. It has several requirements, but the most important one is simple: no falling in love. This serves Tachibana well for the most part. However, while he's on the hunt for a new partner, he finds himself having to reject potential candidates, as they admit that they might end up falling for him. Tachibana is about to call it a night after hunting for a sex partner when a new guy approaches him.
The man is very handsome but very tall and much more masculine than Tachibana usually goes for. Tachibana immediately assumes he's a top and clarifies that he is exclusively a top. But to Tachibana's surprise, the man says he's a bottom. Again, the man is not Tachibana's usual type. However, Tachibana loves to dominate, and what would be more satisfying than dominating this big guy? So, after explaining his contract with the stranger, the two agree to the terms and head to a hotel room together. Everything is going well with his new bedmate, Kuzumi until Kuzumi decides to turn the tables.
The exclusive top Tachibana suddenly finds himself on the bottom and is thoroughly dominated instead. Tachibana is ready to break the contract and forget the whole thing, but Kuzumi has no intention of letting Tachibana go. And as much as Tachibana doesn't want to admit it, he finds himself craving to be taken by Kuzumi again.
