I don't know how to write the protags names but let's go.
After death they both go to different alternative universes, the one rn is about OG Blonde and his happy love story, they do end up together and have children in the end. Seme doesn't know about anything that happend in the first story, he has a few nightmares but only that.
The third one is messed up because it's about OG Dark Hair. He's full of rage and pain, and his version of the Blonde knows nothing about first universe either (also innocent, as Rafael is alive and well).
They never truly met again. They just end up with different versions of each other, one is in a happy relationship after healing and the other can never forget or forgive.
Clough is sooo problematic. I thought he would learn and live well with his kids atleast but boy was I wrong. No wonder it takes them three lifetimes to just get things right.
I fell bad for just everyone in this manhwa.
