I don’t think they will be romantically involved until the prince is an adult and yes it feels like he will be the one to initiate things, not uke.
On top of that is the big difference with their authority, like can Mc really say no to a freaking prince?!?(╯°Д °)╯╧╧ hell no, even if he's a little shit kid who seems interested in Mc, trying to get him emotional （/TДT)/
Age gap does not automatI ally equal grooming/pedo. The crown prince is blackmailing/threatening MC. Even if he is older, he is still a victim. Older people can be victims, younger people can be perpetrators. Context is key. Now if the argument is meant toward the author for including this underage/adult trope, that I could understand more.
