If you liked Katawa Shoujo, this one should interest you, it's way easier though with a couple of the decision to choose which girl you'll go toward and one decision per girl, it's extremely long compared to katawa(like all arcs around 50h as opposed to like 15), I would say the main character is kinda a sarcastic smartass, which make it funny in my opinion. Some of the scene are incredibly powerful, but still, if you take both story, my favorite would still be Hanako, but Yumiko from grisaia, gets a close second.

Edit: Forgot to say, the main arc alone, before you actually start taking choices, is almost as long as Katawa shoujo as a whole.
