He is the biggest victim/most pitiful person in this story not Eleonor. First is he have to share his fiancé with 2 other people and their child since he has the dna/blood of all 3. Plus in the first timeline the blonde guy is the loyal servant of Gray, who Fenrir's parents throw to him during his rut. So that he can get his revenge on the duke's family. I mean, it was his father who is to blame for what happened to his mother not him. He was still a child when it happened.
Fenrir was not and fault at all. Even in the 1st timeline, Fenrir was a victim. He was in a rut when his dad threw an omega in heat at him and locked the door. Rut x heat. He could not have fought threw such situation. The blonde omega got pregnant from that one time. The baby needed the father pheromones, so Fenrir had to keep seeing the omega. He would've been a villain if he abandoned his own child. He kept away from El because of the guilt. He was too ashamed to be with El because he felt he betrayed El. But what was he to do in such situation? There's an innocent child involved. El understood Fenrir predicament. He knew Fenrir loved him more than anything and Fenrir is hurting. He didn't off himself because he felt betrayed by Fenrir. He did it to free Fenrir from their tragic situation. Btw Fenrir is just an heir to the dukedom. Even if he was the duke, there really wasn't anything he could do about the omega bearing his child.
