The story is SUPER LONG and everything is locked behind the story including the QoL upgrades.
The combat sucks for almost half of all the chapters. but actually pretty fun once you get the hang of it. Minus the item farming and save scumming for certain mechanics.
Pretty good if you enjoy a very slow burn story and daily life aspect of it. The porn is pretty much the usual 'Fushidaraitei' style with many options for casual H, but the H events are much less frequent for how long the story is. At least NPCs outside of the three main girls have repeatable events.
Also, Romario (pink hair with hairband) is a boy. Don't be fooled by his appearance. Asking him to accompany you to the Love Hotel is funny though.
