Honestly i do hope what you want happens but considering Jiyoung's position it'll be difficult for her to move especially bcos of who the opponent is. Noona is the president of her group plus representative awakener of SK plus the balance of power is currently unstable plus even if he's bastard he's still disciple of top10 so she can't just make any selfish move that might later endanger their position.
While with Jiwoo, he isn't in a position to worry about, only thing is that he's visibly weaker than that bastard. Tho i think if he ends up fighting it'll different from the usual spar. I remember Jiwoo is usually calculative and holds back a bit when sparring but that one time with loser Duke back at the world academy betrayal arc, he abandons calculations and goes all out when he attacks. Sure that as usual it'll be a difficult fight but even i would punch without remorse if my friend got hurt by someone undeserving.
Love Jiwoo but I'd like it if Noona stepped up for this... Cause like, that's her brother. I don't know if they're close but Noona is the boss of Korean association something right? Shouldn't she stand up if her people are hurt? And of course, I know it's not Noona's fault / responsibility to deal with Jurion's obsession, but I can see Kayden or Pluton or Kartein joining to help Noona. I think Jiwoo might level up with Gestella's force control but otherwise, I do agree with mommy he's overestimating himself here... Hope the rest of the gang is informed and talk Jiwoo out. And would be nice for Jiwoo to see how Noona kicks em' butts XD
