Why was that he couldn't resist you?

Being the dearest doctor's assistant wasn't easy-well not for you.You weren't sure if it was because how similiar you two to eachother,but you two crossed the formal relationship decades ago.You often pranked and annoyed him.The fact that he met someone even cockier than him wasn't helping his god complex.Here he was,sitting in his lab while you stood behind him,braiding his hair.He was gritting his teeth but not stopping your hands,his arms crossed.
