I saw the other person as a friendly flirter and it seemed like Kaede took it light heartedly? He laughed more with him than with his actual partner. The fated mate initially didn’t know they were in a relationship. He was pesky for a few days, but even in his heat he truly did not want anything to happen. He simply wanted his own protection without getting in the way of their relationship. That’s how I saw it at least.
Kaede said no to Azusa too but would you look at that, he was forced to be his mate. Atleast the second omega wasn't forceful, he was annoying but not forceful.
Don't get me wrong the couple was toxic
But the other omega was a bitch like you know he has a mate so fuck off??? There are many other alphas ya don't have to steal an alpha who already has a mate + the alpha clearly said No
