I'll refrain from hating her mom until something drastic happens. The backstory of Takae's mom explains the source of the abuse pretty well. No matter how it plays out, shit is going to happen. It's either going to be shitting on mom or shitting on the others.
I can't decide whether it's a good thing or a bad thing that she didn't say it this chapter, but it is a good thing it wasn't done before the party they threw Takae.
This is one of those rare breed of manga that makes me not want to have to wait until the next chapter is available.
For once, I'm reading a reincarnation story that has actual weight. Not just, "Ou lah lah, I died from a tragic car accident and then I'm suddenly another person! New me, new life."
