Looking for a manga where the side chapters are about the 2nd main couple, and they had a contract dom/sub relationship. When the previous submissive partner appeared again, the dominant wanted both submissive to "entertain" him to show who was the best submissive, but the current submissive ended up using the safeword because he couldn't go through with the act.
