My 2 cents: the basic idea is really good and has a lot of potential, but unfortunately the game loop feels a lot like a sandbox: you do the same things over and over again and skip most of the repetetive content just to get some stats up or down. This is not really enjoyable for me.
Also, there is a lack of decisions at the moment and it is like a kinetic novel: the only real decision the mc can make is if he calls his girlfriend during the day or not. Depending on that, their relationship deteriorates or not, but the story and the girlfriends development with the bad guy stay the same.
On a matter of personal taste, I'm also not a fan of "drug corruption" or "mind control" stuff nor creepy behavior: based on the preview, I hoped for an evil, mad genius, not a horny lab assistant as antagonist.
While the basic story idea is really good, the game doesn't use this creative basis and falls into common, imho boring tropes of this genre (drugging; creepy guy who jerks off and ejaculates on unaware woman, that's just pathetic. Basic attempt of "seducing" the woman instead of dominating her). On a positive note, the antagonist is not black and looks quite average, so that's rare and appreciated.
I'm also missing player / mc agency, so making narrative decisions that impact the story and the characters relationships. Obviously I want the cuck / husband to lose, but at the moment it's just "work, work, work, see her sleep, after x repetitions have a unique scene that shows her development with the bad guy", which is not really engaging and interesting.
If this is all intentional and on purpose, well done and good luck to you, don't mind me then. The game is surely better than most other games here.
