no shade towards Theo, but man, he needs to grow some back bone

Indeed, Theo is a law abiding citizen, but have you forgotten he works in a law firm and is a lawyer himself? Sure, dealing with Gunner is already hard thing to deal alone, but he's capable with dealing at least a case against that man. It's his reluctance and hesitance that's holding him back from actually freeing himself from the toxic cycle he had grown used to with the man he once loved. Theo wanted to believe Gunner would change—that he would do it for the sake of their future because it didn't matter whether Gunner had money or not. It was Gunner's sincerity when they were young that drove Theo to grow false and lingering hope, because he still hasn't fully accepted that Gunner won't leave the dirty work-life K put him in.
More or less, it's his lack of security and trust that puts him in the situation he's in. And that issue is slowly being healed and taken care of when Theo's with Dylan. The blondie isn't as innocent, but he's the one that doesn't bring Theo the feeling of being suffocated in such a repeated routine.

up to where I'm at the novel, jun and yohan's relationship is so different compared to the manhwa rn. I regret(?) reading the novel because the drastic change almost made me cry

spoilers: jun and yohan were still in the same class during their third year.
jun also found out that yohan had liked him but HE STILL DIDNT REVEAL HIS FEELINGS FOR HIM.
the only difference was that they had a huge falling out arc (which i recommend reading the novel to find out why they fought). jun ate alone, pretending to be engrossed in studying,, andd he and yohan practically don't even talk to each other anymore unless yohan's humiliating him. but don't worry it'll change after several chapters.

jun found out how cold yohan's family is and treated him like an outcast. Since he felt so bad and didn't want to see the usually lively and confident yohan he saw in school, he ate dinner with the family and yohan felt embarrassed. When they finished dinner and returned to Yohan's room, they fought and things went south then. I think Yohan has bpd lowk
also can ygys all collectively agree that doha is indeed under bada. cs wym bada’s body remembers he owns doha. Not the other way around
