I blame the parents for putting that idea in a young girl's mind and the stupid tradition of marrying ur siblings bc of "magic" capabilities that none of them have except for the chief

If the parents die, I wouldn't mind. Doing us a favor for suggesting such a stupid tradition. If the sister dies, then I'm good on that too. But fat kid would be sad, so he can have her if she gets cured from that black smoke thing she communicated/possessed with

His sister be crazy as HELL! Like sister...Chill...Like there's plenty of boys in the village to choose from and even if you caused trouble he STILL wouldn't marry you, aka your efforts at futile! I wish someone would smack sense into this little girl...ヽ(`Д´)ノ
