Seeing Joonwo be so alpha hypes ya the fuck up. It's a good feeling to see where this dude started and where he is now. He better not lose to that bitch's bf tho, because if he does, all this alpha-ness would go to waste and I'd probably find it difficult to take him seriously in the future. (Honestly, I don't think he'll lose. He's fought against Taeyang, who's the 2nd strongest character after class prez and managed to hold his own to some extent. He should be fine.)
Also, I never doubted Yuri one bit. If she really was in on the bullying, it'd contradict her characterization and backstory. (Hamin's still best girl tho, but Yuri is literally right behind her.)
