I can't believe people have to explain to you why their relationship would be predatory.
Honestly it shouldn't matter when a person caught feelings, what truly matters is their previous dynamic before they even turned into an adult. If their dynamic is guardian and child then no they should never be turned into love interest because those doesn't mix and shouldn't mix. Adults can still be a victim of grooming from their childhood believe it or not. Honestly adults should be more busy guiding younger people into the right path rather than finding ways to make them their lover.
This whole thing shouldn't have to be a debate just accept a simple fact that adults shouldn't fall for people they met as minors.
Oh and don't give me that western romatasize bullshit I live in Asia and yes authors are willing to destroy their well written works for pedo bullshit. Books and literature are powerful it can very much affect reality it can cause a revolution to happen irl fiction or not. That's why when people see pedophilic bullshit in literature they tend to call it out and not tolerate it.
Find a lover your age babes its that simple....
I hope gangster guy here stays as a guardian worrying about mc's relationships in a completely platonic way. For me it would be weird to see a guardian/father figure do a complete 180 and suddenly becomes a love interest just because the kid he looked after has now turned into an adult.
