Hey,what about checking if you two have common interests. I mean you could join clubs and hang out at some place. And as you both are in the art class(can you explain that in a more detailed way later?)it must be no biggie.
Remember,these things don't belong in the love life:
Age:it doesn't matter as long as both of you seem okay with it.
Fights: they're important to have in every relationship but do not bring that up all the time.(I mean;ouch)
Betrayal:as long as both of you love each other truly(and do not backstab)but you are more than welcome to take your revenge if he backstabs you.
PS:I just joined KS now so apologize me for answering after ages.
