Id say this review goes into 2 sections, 1st being spoiler-free and 2nd having minor spoilers, a little bit of a summary.

It tends to be that at times you find yourself (sometimes for the longest time) completely ignoring some sort of your deepest, most desperate feelings, desires etc. and you mask them with the capabilities of your mind; you hide those feelings and desires by quite simply making yourself believe the more or less opposite of what you truly think, feel, desire and believe. This, when built up, can at some point in time make you feel very troubled. This fast-based story speaks to me that exact thing quite strongly. Aside from clear, strong sexual desire shown from the characters in the novel, which in itself can mask your true feelings of love and yes, that means it can create fake sense of love too, with you confusing it with the sexual kind, that is not necessarily the case in this visual novel and the sexual thrive can be a perfectly fine beginning to falling so deeply in love, that you really find yourself completely hopeless. That in itself is quite beautiful about this story. The beautie of life is having someone to cherish, to hold, someone that takes away your deepest feelings of loneliness and desires and i believe that once you've found the one, no matter who or where they be, the mutual desire to become something more... to become lovers is a very beautiful thing. The road is always bittersweet, but thats the beautie of it! As i like to say, overthinking is usually a bad thing and limiting it and following your heart is completely fine; if your heart truly tells you, say, that the hesitation is unnecessary, so be it. However, desperation makes people do stupid things and sometimes patience really is the key, however one must also not forget thats chances can just slip away, sometimes forever... so there really needs to be a more or less of a balance and evidently reaching that balance is not by any means easy, but neither is it also by any means impossible. Awkwardness, misunderstandings, uncertainty and the such is a part of life and you do sometimes find yourself looking back at those awkward and silly moments, chuckling in warmth or filled with regret: the balance of these memories makes life special. Anyway, this is not at all me reading too deep into the visual novel itself, its just that these thoughts strongly resonated within me, while reading this visual novel. In an indirect way it was quite relatable.

So, more of the visual novel itself~ At first you feel a lack of context from the sudden start of the visual novel, but after a while im pretty sure i got it right; its either that Ai lost her job and while thinking on alternatives remembered his brother writes eroges for a living and decided she wanted to try her hand at it aswell, while reviving her feelings for him and/or its that she was simply using the loss of her job and wanting to get into writing eroges (while ultimately enjoying it a ton) as an excuse to finally make a move on her beloved brother via using her lack of experience into writing as an excuse to get into lewd situations with her brother by playing out various scenarios so she could get better at writing and during all of it giving out various hints to the brother. There is also the confusion about the knife scene: did she simply try out a yandere approach in her story and desided to scrap it? And then there is the part about Sayuri... We learn that Ai had some photos of showing Sayuri lesbian games, so Ai used those photos to get Sayuri to help her seduce her brother even further and to give him the final push to confess his true feelings to Ai? Was she using these roundabout ways to safely confirm whether or not her brother would give her a stereotypical response to her love, so she could use the entire situation with her wanting to learn how to write eroges as an excuse to not weird out her brother and make things awkward in case he did give a stereotypical response and did not mutually love her? I believe that to be the case, but basically i feel like the only con would be the confusion found throughout the story. All in all tho, its a very enjoyable piece and therefore very much recommended!
