There's a difference between an adamant young one, and this guy with monstrous strength acting on instinct and using the MC's unconditional love, care, and loyalty against him. It's a very unfair power balance. The MC is literally getting taken advantage of. But otherwise, throw guardians who end up with their kids in jail!!!
I wouldn't think this as grooming cause I feel like he is older than taehyuk even though he is in his young/child version of himself when they met. Yk the dragon thing but ig yeah for some they will think this as grooming cause of their back story and grooming is not good too, I just hope the author put a note or like a hint that I'm right about him being older than taehyuk when they met
would it still be considered grooming if the older person has no intention of romantically loving the younger one? its just that the younger one is adamantly in love with the older one and the older one keeps on rejecting them before deciding to just ultimately accepting the affection of the younger one
