This is a very basic Netorare story. It is told from the perspective of a young couple who are getting treatment because she has never had an orgasm. Then a young guy (re-)enters their life and spices everything up.
It's a relatively realistic, low key story. It's based on clichés as someone complained, but on clichés that actually occur in real life. The art style takes some getting used to, as the characters have intentionally weird eyes. But I can respect the artistic choice.
As of version 0.5, what exists so far corresponds roughly to an erotic short story, with some very nice scenes before the sudden ending. The quality of execution is very high throughout. I think it would be unfair to give this less than 5 stars, even in its current unfinished state.
