Holy hell, Murakami's mom is crazy, she either killed her husband and son or they staged accident and ran away...
Seeing how dependent on the drug Kurohaneko is and first chapter Murakami ending their relationship, guessing that Kitsuka having a crush on her senpai might be an open book.
Kotori grew back her left hand? Could have sworn it fell off in previous chapter...
Murakami is chill, no nosebleed or going into shock after seeing some breasts like a typical mc.
