I laughed at Mudbutt-kun (whatever the blonde third wheel's name is) eating that poisonous food and getting diarrhea. It's been so long since I last read this I forgot who anyone was.
For real, if you drop a series after the slightest hint of two-timing/cucking you need to grow up. Hopefully when you actually get into a relationship you aren't jealous and distrustful, I was like that back in high school and my first couple of relationships didn't last long because of it.
