great game but how do I unlock all endings?
How do you get shiori ending?
If you wanna unlock all the endings then you have to lose against each girl every day. After this on the 4th day the girl you have interacted with the most will appear one last time to get between the MC and Shiori, so you need to see this three times just a heads up that Aoi forces the MC to kiss her multiple times so the love towards Shiori has to be around 50-60 I believe to not succumb while Rin + Maika you can just skip and go directly to Shiori. There are also 3 hidden endings one each for the girls they all revolve around the MC having only 10 love points left so that the MC ejaculates instantly and then during the first day make a false confession to Rin, during the second day when Maika offers to give food to the MC say ahhhh and lastly during day 3 when kissed by Aoi.
After unlocking all the endings you can get the "true ending" which is pretty much just a little bit of more talking with Shiori and a kiss while the MC confesses.
Also my take on the game was that pretty much Maika being the bossy tsundere girl and that while she doesn't show much love/chemistry for the MC during the game once it's get's into the epilogue she is shown to have pretty much fallen for the MC and seemingly would have been a great match for him. When it comes to Aoi I honestly believe they could have just made a game focused around her and the MC and it would have been good, she's crazy about the MC and while she at first can't understand her feelings as shown in both the game and the epilogue she loves him above all and the fact she has to distance herself from the MC for fear of her raping him cause she is so crazy about him say's something, a bit unclear of what you would call her type though soft yandere girl or maybe a bokukko is more like it?
When it came to Rin it's kinda hard to place her since she doesn't really like the MC and is more just taking it as a game and even if the MC falls for her nothing will come from it. Lastly Shiori well there really isn't much to show why the MC loves her outside of the fact that he pretty much falls for any girl showing him a bit of kindness or any kind of erotic stuff there also isn't much interaction with her outside of the fact that the MC spent so much time with her and they are both otakus, but even after they get together and have been together for years she seems super distant and don't really seem to care for the MC while also feeling like she's become even more introverted.
Lastly the MC is seemingly a total M with low confidence but with a tendency to easily fall in love with girls. I honestly think that the MC if he got together with Maika during the epilogue, not as much during the game since at that point she seems to not have started to like him or at least not as much while the ending also explains she treats him as a slave at school, which makes it unclear if they stay together after high school. Aoi on the other hand would probably be a good match for the MC at any point and it is even mentioned how being with her makes the MC happy and also boosts his confidence. Rin well the MC can't really end up with her outside of becoming her client for sex in the game or end up alone then later on in the epilogue she somehow has come to the conclusion that she is disgusted by the MC + Shiori's relationship and wants to stain the relationship by having the MC stay with Shiori but cheat on her with Rin.
Thats at least my take on it.
