It's few 4 or so chapters are solid and I feel do the very interesting concept justice. I think the author got too caught up on why time would repeat and the mechanics of it instead of just looking at it at face value. And I get what they wanted to do with the ending, it's just the part proceeding it was so convoluted it distracts from the meaning. That's really the perfect word for it: distracted.
I remember basically everything but the name, it was a manga with a couple volumes that takes place at a boys school. The mc is this sort of grumpy looking dude who, after seeing him almost get assaulted, protects the very feminine bottom. The mc and the bottom love each other but the mc thinks the bottom is scared of men because of his past experiences and the bottom just thinks that he's protecting him with no feelings behind it. Its one of those stories were everyone is gay, there's a chubby gay school nurse, a strict gay teacher, a taller older openly gay and experienced student who's past love was teased at the end of the last chapter. It was pretty light on smut and I'm pretty sure had none for the first few volumes.
I guess there at least won't be as much Vercion rape for the time being, so that's nice
