The story so far (might have some tidbits overlapped, but is mostly accurate)
MC worked on the Nightclub, in there he gained a lot of self confidence and learned how to properly read and treat any female, while maintaining sexual relationships with practically all the female staff, from there he get into a relationship with that cute Goth girl (I'm not so good with the names, sorry), then they break up due divergence in their paths / career goals, then he get with Bethany, and is recruited to work on Mirsky, highly probably at his mother behest, unknowingly by him, Miranda set him in a path of going around the globe swooning any girl related to the company, and even his own step mother, in detriment of the relationship with his father and sister.
Bethany breaks up with him since he was actively cheating on her with at least 5 girls, however Miranda had already set in motion the AI projects, in which MC is a fundamental piece, MC understands that all the other girls are fundamentally his ego out of control, exploits for the sake of conquest, and maybe he did it unconsciously, since he learned to literally lure the females to sex, well... because he was practically groomed by the girls of the nightclub into a perfect seducing machine.
MC realizes that Bethany is the right one, he goes to talk with Miranda, to break the contract, and be free, Miranda informs him of the Echos, and he is introduced to 2 active ones, and the uncompleted body of Skylar, he get convinced of not break up with the compaly and to have the surgery procedure that will fuse P.A.I.G.E. with his brain, meanwhile Mirsky had already employed Bethany, to sweeten the deal for MC then after the surgery he is put into cryosleep and sent his merry way to Elsyum.
(This is my speculation) Synthstar somehow got wind of Mirsky (industrial spionage or something along those lines) project on developing AI's so they wanted to bribe Bethany to gain a more direct contact with the core members (in this case MC or Lexi) related to the Echos project, and maybe steal the developing data of one of those, specially the most prominent one, P.A.I.G.E., so, since they couldn't do it before MC was put into cryosleep, they gathered intel on MC in order to put at least 1 operative in Elysium, that could enter in direct contact with MC, banking on the fact that MC would try without even being aware of it, to seduce her, in this case, Ishani.
What isn't clear yet is how come MC ended in the all female spacecraft, since he was put on the all male one, is not clear if it's a ploy by Synthtar or Mirsky,or a 3rd parth that we are unaware of yet.
