All I can say I'm glad I'm reading this at night and not where my family can read what I'm reading over my shoulder. Peeps beware this be spicy.
Cue Chapter 37...
ML:"We found out the truth"
The father b***slaps the crap out of the sister
Then the sister gets even more mad and wants to kill the FL.
(this isn't what happens but I can definitely see the next chapter like this.)
This story turned into "I'm terminally ill but my brother is a reincarnated god of medicine"
(I still love this story and hope that we get another season for the anime too.)
