oop this game is Lowkey yuri too LMAO there are very strong subtones -- i'm not a big fangirl over fictional couples, yuri or not, i think of mimi & domo's relationship not as something to fangirl over (it's so toxic) but them being lgbt+ does add a layer of complexity to it. a lot of ppl just think "omg cute gay women" but there is actually a lot more to be said about the ways they cling to each other in a world that is generally not as forgiving to lgbt+ couples
miss's real name is not confirmed nor mentioned in-game so that's a secret i cannot tell you! we may hint at it in the sequel though
also the blueberry/strawberry thing is cute is that bc of their color palette? i imagine miss as more of a blackberry lover she just gives me those vibes + she likely couldn't afford them for a while (this is the only lore drop ur getting LMAO)
regarding the good ending i wouldn't say there is any positively good ending to like any of nii and i's games? in this one for example, you can find pretty long comments i wrote in replies to other ppl dissecting it but it's supposed to show you how disappointingly hypocritical these characters are against the backdrop of a society that gave up on them
