There is something about this story that is chilling to me.
It's a good thing to have in a horror story, but there's something about the loss of control that the MC experiences that in a sense takes my breath away.
From my view, they are chained to Aster, even if you take the route where the MC tries to distance themselves from him, their world is hazy, fuzzy and numb without him. Even when they know that he's not exactly a nice person, and his mood swings put real fear into them, ultimately they cannot stay away. They cannot find anything within themselves to be mad or angry when Aster waits a few days before messaging them. They roll over when he offers a time to hang out and when. They nearly have a panic attack when the choice to confront him about his absence and unexpected arrival comes back around. The way where when the MC rejects him taking them home they have a panic attack so bad their mind literally starts to unravel.
Another model even texts the MC asking them out, and yet they receive no response because they are not Aster, and there is no need to the MC to fill the hole inside them with a romantic relationship when all the muddied pieces of them call for Aster.
They talk to friends, but it is not enough. It seems to all be surface level from their numbness, Nishat and Bunni may care about them (or not, we haven't met them yet), to the point where Nishat doesn't know you grew apart from Aster, and Bunni seems to be a work colleague if the fact the MC's boss is asking about them says anything. Not to say you can't be friends with a coworker, but everything about the MC's life is conveyed perfectly with the backgrounds: Empty, Devoid of any faces they care about aside from Aster, and almost monochrome in pinks, purples, whites, greys and blacks.
The soundtrack seems to also convey that to me as well, because there are dreamy notes to it as if MC isn't completely rooted to the planet.
The endings were also very good, I made sure to play through them four times to get different flavor texts, and it's all so very interesting, because while I really have no idea what the heck is going on, it really seems like Aster is influencing the MC to the point where it's mentally shaking them up and almost puppeting them.
After all, how can you have your favorite love story that you wrote between two people when one of them (At least mentally) refuses to participate?
I can't wait to see more from you, I will be keeping an eye on the project because I can't wait for what comes next!
