There isn't much of an actual plot in the end, it's really all about fun and giggles and some good ecchi here and there until the end with a decent length that's nor too short or too long.
A manga like this with ecchi and absurd humour is right up my alley hence the high grade. I also liked how the dynamic between the main male character and the main girls developped a bit as the manga went on, it gave me the nice feeling of watching a group of friends who are just messing around until the end.
