That bitch is faking it ... or as someone else suggested she lost their child and went extra crispy bat loco with jalapeno sauce. I believe it's the former. She WILL fuck over both you and the sister.
Edit: Personally, I would have observed her the first day. Then found out where the heffer lived. Then visited her at night for the kill. Then again I can see why the author may have gone this direction since it does introduce some more mind fucking from Midou.
I thought this would be a short manga, but maybe not. I think she's faking it and the doctor's in on it cause they're banging. Pretty stupid of him to attack her in front of all those kids. Watch her for a bit. Now he looks like the psycho.
Hell no it ain't ganna end there @jimkage
It's not the translation it's you... It was already explained in a previous chapter that the chick next to him right now is her younger sister... of the one that did the shit to his second GF (Second GF younger sister)
Yea, amnesiac or (probably) not, great fucking plan letting a psychopath and murderer work with children. Also, they're trying way to hard and making MC-kun look like a chuuni edge lord. Like god damn. The hair, face and behavior is just so cringey.
