Edgar and Luca have a love hate relationship
If Edgar is mad at Luca he'll throw a canvas at Luca
When the others are suspicious if Luca and Edgar are dating Edgar denying it embarrassed Luca would stay quiet while being scared of what would happen if he told them (get paint thrown at him etc.)
Edgar when he says he would draw Luca he'd draw a trash can as a joke but would make little sketches of Luca in his notebook without him knowing
If Luca were to get sick (yes I know they're dolls😕) Edgar would pretend as if he didn't care but actually cares about Luca and his health
Tbh I'm bored that's why I'm writing this
