i thought that was her friend from earlier and they made plans to make a fake golem heart that looked real to slow down his plans while they made their own plans to take him down. they made the plan in front of husband lime and lime was super jealous of him and wanted to kill him lol. but the dad is planning to brainwash the brother to kill his sister which is why he's tied up and resisting.

Ok so why would her brother sell that to her dad? Does he want him to summon the devil, does he know she got the antidote? I can't remember. I'm not sure if it's my mind going in my older age, if it's because the story is coming out slow, the translations are hit or miss, or what, but yeah I'm having trouble keeping up.
Anyone wanna explain this chapter a little? If not no worries, I can try to go read past chapters over again, I just don't get all the brother stuff. I thought he was mostly on her side...
I'll comment my theory about her dream in its own post to keep thoughts and the two seperate themes organized.
