Finished My Little Monster and Problem Children are coming from another world, aren't they?
Both have a read the manga endings, but Problem Children I found more enjoyable.
Little Monster doesn't have the payoff I was looking for and left every single relationship open. Solid RomCom, just didn't get the payoff it needs to be a good series.
Problem Children suffered the same problem as Noucome (My Mental Choices are Completely Interfering with my School Romantic Comedy) only 10 episodes, but really good.
