Please help me find this bl manhwa

So I don't know if the characters are main or side. But the thing is, the uke is like black hair and is a police man, not alike prison guard or something and the seme is a blind hair and muscular and dazzling and he is a prisoner and he likes uke very much to the extent that he always wants to be near uke and seme is probably in the prison by his wish but not sure about that. And the manhwa I think had alpha beta omega or like pheromones concept. Or may be not. The ukes senior told him like be aware of him, then again, seduce him or do anything but keep him in control or something like that. The top looked powerful even when inside the prison, I think he probably had a cousin or sister like that who is with the police man or somehow of high post(she sleeps with him for the protection of the top). There was even one scene where the top sleeps in his rut clutching the passed out uke.
