I've played some slow burn games, but this might be the slowest of them all. I'm not complaining though, this is right up my alley. I'm all in for some wholesome stories in h-games.
I think the intro scene is kinda unnecessary though. Given how long it takes for both Rina and Hana tell MC what happened to them, I think the entire first half of the game would work better if we were in the dark as much as MC was. I've a few gripes with some Rina scenes, but I'm not a fan of the "dom brat" archetype so maybe it's that. She's much more charismatic than most other characters like this though, prob my favorite of them all.
And oh, in Hana's bonus affection scene, when she is reminiscing her old brush. "Hurt" doesn't have a past principle. "Hurted" had its uses but it's now archaic. It probably stood out to me because the game otherwise it's pretty well written. I'm used to furry games having broken English at this point, normally I wouldn't point something like that out. lol
