I was just about to through my incredibly expensive device across the room as hard as possible. The cutesy art style but heavy themes and jokes are always keeping me on edge as I never know when something serious might happen.
This story is slightly reminiscent of Happy Sugar Life for me.
I thought for a second the story was going to get Bibi some good person redemption by being super selfless and saving who she truly loves over herself just like Satou Matsuzaka did. Although, Bibi is debatably slightly more loveable/forgivable than Satou and as far as yandere's go in general. I'm glad it was just a little prank by the author man they are good.
