now that i can remember where my posts are brnswick Naya Rivera for a romance line - she'd be the one that pretty much makes his jaw drop and knocks him on his ass when he's being an idiot, makes him forget how to form coherent sentences, etc. etc.
Josie Loren for a best friend since diapers. Nicole Anderson as the other best friend since middle school. Kaley Cuoco as his older sister (25/26) and Jesse Spencer as his older brother (28/29). Parents would be pretty dope too.
