Unanswered questions

I enjoyed it for what it was but the plot was all over the place.
Why did the seme get so obsessed with the uke in the first place? Because he was "arrogant" and he got intrigued? Are we supposed to believe he had never met an arrogant person before in his 28 years of life? Please.
How come the uke didn't give a single fuck that the seme paid off his friends to lie to him? This is super disturbing, who would ever trust their friends again after that?
How come the uke was depicted as an arrogant privileged asshole in chapter 1 just for it to never be mentioned again afterwards?
Why the hell did the uke fall in love so easily? Isn't he an heir? Is he really okay going out with a sociopathic man who stalked and preyed on him?

This could have been way better with two volumes imo.
