So spiritually, they didn't end up together. The souls of both Aeroc and Klopp from V1 were seperated into two different alternate reality.
In V2, Aeroc from V1 meets the past version of Klopp. In this timeline, only Aeroc can remember what happened from the past timeline (V1). This is why Klopp only gets to see the memories in dreams. As you can see, it focuses more on the POV of Klopp.
I honestly think that this was actually what he felt towards Aeroc from the very beginning, and admitting it would be easier if it wasn't because of his internalized "homophobia." Alpha-Alpha relationship is somewhat frowned-upon by their society plus, the fact that he sees Aeroc as someone superior to him hence, the demented behavior of Klopp.
While in V3, the Klopp from V1 (the one who abused Aeroc) meets the past version of Aeroc.
As far as I can remember, Aeroc will tranform into an omega later on. I've only read up to this point.
Honestly, I wanted to see both of their V1 version be on the same alternate reality. Makes me wonder how they would deal with each other knowing what had happened between them, will there be a change? Perhaps, Klopp will take the courage and Aeroc will be allowed softness instead.
