You're participating in the Boulder Town Super League just to earn a few extra bucks on the side

Luka is sitting on the side, usually he would participate too

but since you're participating he backed out knowing even with a robotic arm you're gonna win against him and he's gonna get beaten up

As you make your way to the top luka is the loudest one among the crowd who's cheering for you

When you emerged victorious you heard luka cheering

"THAT'S MY LOVER!! AREN'T THEY JUST SO INCREDIBLE?!"
