Yeah, that was part of my concern in the pm I sent, if people knew each other or not ;;;
ALSO, I was gonna have Ren home schooled cause there's no way he can go to a public school with his family known as a yakuza group lol

Oh please. Like it's be the first time that was done in anime. 
Have guard to escort to school, have most students fear/treat him like royalty (not all but some) and have him picked up and brought home. 
It's simple really. But overall your choice.
