Beta is a doormat to Alpha yet keeping Omega close because he likes being pampered.
Alpha is a bitch who likes the Omega but is keeping Beta close by just in case
Omega is a total nutcase with complete control of the situation. Is a horrible being all in all and is hiding in his sweet facade he shows Beta.

In the novel, you could clearly see the MC’s struggle to get away from the seme but the power imbalance between them is too great. The ML is obsessed and spoiler alert, at the very end the uke just went I could never get away from this dude might as well be accustomed to this life with him.
The author has this little extra where he interviewed the MC and ML and it was clear she is aware that ML is a POS and that he r*ped the MC.
Also, it would take a couple of extras before they actually get together for real. So yes, the actual ending is MC just relenting to the ML. And the actual reconciliation would actually happen in the extras.
Dan was right not accepting the offer, not because of the bitch Jaekyung of course. It’s because it’s hella sus and the drug may not be even true. Or everything promised to him is just… well, promises. Better stick to Jaekyung for now.
