To be fair in this comic it is also a crime, he just isn't turning Su-ah in. They mention it twice I think (once when the MC is mad at him and yelling through a door and once when Su-ah is yelling at the hot old alpha).
I am surprised by the amount of people that don't get that Su-ah is supposed to be wrong, the whole hottness of the situation is that he's obsessed and slowly catching his obsession. (Does he have sympathetic traits? Yes. Does that change that the whole fetish of the comic is supposed to be obsessive love? No.)

Am I in enemy territory because wtf is this? This is borderline fcking Stockholm syndrome, Su-ah you piece of shit you're lucky you're pretty and people are defending you but I can't get over what he did and how he's acting. BOO FUCKING HOO you're being treated like an object? You have been non-consensually altering your best friend's hormone system to make him dependent on you for Y E A R S!! Which, in a proper ABO universe there would be strict laws against, making it a literal CRIME.
Take your pity party elsewhere, I can't believe you got MC acting like this, poor guy. This is a psychological thriller to me.
