So can anyone explain to me what’s happening?? I feel like I skipped a huge as drama scene?? Like what happened to his sister, and why are they talking about marriage (I thought she has debt to pay and ran away) also who is that red headed bitch and talking about marriage and celebrities?? The fuckkkkkk I know I haven’t been paying much attention but how did we get to this scene again?? ╥﹏╥

Hmm, the redheads husband ran away with Mong's sister and Mong is staying with Jaeha to kinda compensate for all the medical billa Jaeha paid for his sister or in general as a hostage since his sister ran away.
Redhead is Jaeha's sister.
And apparently Jaeha is getting married so what redhead is implying is that in their class, it's normal to marry for business purposes and fool around with others.

So it wasn’t dion or the male lead (because the male lead has white hair the person had like blackish hair) then who was it??

Yep yep!!!
I thought the hair was blonde, but it definitely wasn't black. For others who couldn't tell, gotta look very closely at the 1st strand of hair from the left. It is outlined, and not dark in the middle

Wow your guild leader died by someone stronger than him and you guys who used to be the guild leaders underlings know thing you can kill him?? You do knkw he killed your guild leader right??

I don't think that's what was meant. Notice "person who killed that bitch" not "person who kills that bitch." They seemed to have been calling their old leader a bitch and are saying Gigyu would be their new leader due to him challenging and defeating their old master.
Not saying they won't take that as an opportunity to challenge him for that position, but they seem to have respect for power and run on a "the strongest rules" type of thing.
I’m sorry I’m dropping this because they keep mentioning that she’s a child and not an adult but she’s actually an adult but got turned into a child. Just because she has a body of a child it doesn’t mean that your brain changes. Also isnt she mad that they tried to kill someone she risked her life for??
She was mad and her mind is changing. The poison not only changes your physical age but your mental as well. Slowly but surely she is getting younger while trying to remain her actual age
