just my opinion of what I think of the game, not a synopsis of the game, since the game basically has no story (the parents travel and you are alone with your sister)
about the sister:
compared to other games I've played in this style of love between brother and sister, I can say that the sister is very alive, the developers gave a lot of life to the sister's personality, at first I was even angry at the sister's provocative personality, which is between some kind of sexual provocation with tsundere, imagine a tsundere who treats you badly but likes you and shows that she likes you at specific moments when she lets her guard down, Now imagine a tsundere doing this in sexual terms, laughing when you lose your virginity and cum just by putting it inside, and saying things that make you sad, where the MC literally almost cried, but at the same time she cares about running after the MC on the street at night and in the cold when she sees that the MC leaves the house sad, she drops everything she is doing even without warm clothes and goes out on the street looking for him,
the sister kind of gives off a yandere vibe, since she mentions several times that she is always watching him and knowing everything about the MC, in extreme detail about him, even the sister's gaze at certain moments gives off a yandere vibe, so I would say she is a mix of yandere and tsundere (?),
and of all the games I've played in this style, where the younger sister loves her brother and such, this is the first game in which the younger sister is active and dominant, in which the sister plays a more sexually active role, normally it's the opposite, this is something I liked, as I said, the sister is very lively.
mechanics:
the scene about messing with your sister while she sleeps is good, but it's not the freest, there are games out there with more freedom about what to do with your sister during the game,
I would say that this game is very simple and linear and straight to the point even in relation to the interactions with the sister
One thing that surprised me was the sister's reaction in that moment that I mentioned above, as I said, her personality is really good,
I would say that the game lacks more interactions with the sister and more freedom in choosing interactions, more different things during gameplay, and a longer game time, since the game is very linear and very short, the beginning of the game is very slow and monotonous, I would say that if you get past the first 10 days of playing you will be fine
but before that most of the game's features are locked, you basically just go to work, even interacting with the sister is locked, not by the sister, but because the MC still doesn't accept the idea of incest, (too dumb), since his sister would accept him having sex with her from day one since she has had feelings for him for a long time
MC
mc is the type of skeptical character who has great luck but doesn't know how to take advantage of it, too righteous, always worrying about what is right and wrong and what others think, to the point of almost letting the big luck slip away if it weren't for his sister insisting on liking him, (I would say a perfect cuckold) since normally in these cases the girl tends to give up on the guy who is too straight, but not here in the game.
Observation:
One thing I noticed (and it's hard not to notice) is that the sister talks as if she wasn't a virgin, always convinced and thinking she's the best when it comes to sex, but the game never talks about how she lost her virginity.
I even thought if it was with her father, but I don't think so... or I thought if she was lying, but apparently she wasn't, and she always says she doesn't want any other guy,
She says some things that only yandere say, so I can't imagine how she lost her virginity... I think it was a script break just to make her sister seem more experienced so she could provoke the brother.
conclusion:
the look is good… the sister’s voice is very sensual and feminine, typical of hot Japanese girls.
I would give the animations a 4/10, but for the sister's expression and some certain moments where she sits on the MC, I would give the animations a 7/10, but other than that there are almost no animations.
A short, straight to the point game that is definitely worth checking out since it won't take up much of your time. The MC's personality can be annoying at first because he's very correct or the game's pace is too grindy at first, I would say it would be worth 5 stars if it wasn't so short.
