The ecchi is there, but inconsistent. As far as story goes, it's a fairly decent little harem/sports story. MC is pretty typical, not especially memorable or defined - hits all the standard manga tropes; meh.
This feels like a time capsule of ecchi comedy from 2000s-early 2010s. Artstyle that isn't particularly sexual and would actually pass as a slice of life, writing that isn't well fleshed out, the trope checklist-ticking for a highschool manga, ending that doesn't even tie anything up, the "each chapter should at least have 1 erotic situation".
This is more nostalgic than anything, wouldn't recommend it to anyone though. I only found it because someone translated the pilot of this manga into a language that isn't english and came up on the recent bar
