There's no chemistry between the main couple. If the seme was written as a tsundere, he is more of an asshole who hurls the subject of his affections around but also thinks he's being generous for pushing them away.
The uke is more valued by his brother-in-law. Even if he is a Yakuza, he gave him an opportunity to live and be a better father for his son. Instead, he is painted as the bad guy for keeping his brother-in-law under his wings. If anything, the cop has been a 90% douche.
