it isn't pedophile to be precise. ml whose doesn't disclose that he's high schooler. mc only notice that but they got swept up in a rut/heat and accidentally knotting. mc didn't know and cut off probably of guilt, mc only realised he's pregnant after they broke up. yada yada they meet again. i wouldn't say it's grooming too cause it goes against the logic but you can blame the ml ╮( ̄▽ ̄)╭. like u said ml doesn't disclose that info and had been actively pursuing mc

The only thing that bothers me...
In the past ML is high schooler when they met, MC didn't disclose his specific age yet, and he fokin' know he's still a student. ( ̄∇ ̄")
Is this ped*****
