Nimue like question

So years ago I read this bl manga where the Uke looks like a rough top and he is a mountain bandit. The top is the king(?) and intentionally gets abducted by the bandits and marries the Uke by pretending to be girl.
Too fucks him and later imprisons him also(I think). Also the top tells Uke that if he is able to reach 100th or above position in a martial arts tournament, he is free. That’s all I remember. Can anyone tell me which manga it is?
