thank you for uploading such an interesting chapter I was initially disappointed that they weren't continuing delving into the Kokoro mystery from the last arc. But this was worthwhile, it dealt with some of the built in baggage that comes with chii-chan and it goes back to a premise we haven't seen but have been expecting since Tendou's debut arc his sister was again getting caught up in the moment and playing dress up and at the same time mentally and emotionally scarring their parents.
Yeah, this chapter was a mix of funny and just being pitiful. That last bit was so unbelievably unnecessary.
That scene is basically family wrecking, his relationship with his parents would never have been the same if this wasn't a comedy manga.
