Sneaked? Is it not snuck? (tho eng isn't my first language, i know there are alternatives like "hanged versus hung" (tho hopefully that won't come up in this series lol) but thanks for the chapter!
He should really just abandon them
While it's not impossible, he's like, what, 15-16 max? It'd be pretty hard to just up and leave on your own unless the girl conveniently has enough money for him to stay in a cheap apartment (but even in a 'normal ' circumstance idk how many ppl would have a desire to move out before 18 versus them being like ambitious/moving away for UNI versus being kicked out [other than some schools being strict on working/part time job i remember hearing you don't technically have to go to high school and can work out of middle school, tho i imagine it's not many job opportunities/probably looked down upon if you don't go through with high school unless it's a situation where money is more important and going back to night school afterwards in your 20s or so])
so the moms bat shit crazy.. not bc she sh but looks like she plans on harming mc next time she sees him
theres probably a reason shes like this aswell, maybe something the father did?
Well some ppl just have mental issues that don't show up later in life, like that one with the "should i throw this family away" manga with the mom/wife being unreasonable about the boundary/daughter but i wouldn't be surprised if something set her off just from a story telling part b/c "people changing to an extreme/being a shitty person for no (apparent) reason" happens a lot IRL, it'd be too 'cheap' as a plot device
Hopefully it's done well but other than 'saving him', it'd kinda leave a bad taste if it's like "she's the reason his life went to shit and she 'saves' him just so she can have him all to herself" or something like that
