Stubborn idiot #1/Stubborn idiot #2
Really stupid competitions and arguments in all areas and I do mean ALL areas
Manic pixie genki Jack dragging the broody guy out which is very funny bc Ryu is absolutely a classic flame-haired hothead too he just :/ gets stuck in the brooding sometimes
Straight (not that kind of "straight") man and wise guy
Also straight gay and camp gay
Incredibly deep and heartfelt sincerity and concern that catches the other off-guard
The cheerier (and egotistical) one actually being the one that doesn't wear his heart on his sleeve when something's bugging him and the honest one seeing right through it
Both stubborn idiots being terrible at accepting help but trying to learn together and show each other they can be leaned on
Seriously the way they can flip between "two-year-old hair pulling" and "you idiot. I would die for you" is immaculate. I love it.
