He had some suspicions especially when they were in a weird situation and also when I forgot his name but his bff came to visit, he obviously knew her, and they also got super close cuz of the dead brother. I cried many night during their talks :(. The bff is actually the main anchor as to how he finds out. But anyways, finall she tries to escape with alecia from the house cuz i don’t remember why, and he catches her alone (alecia left her) at the secret gate only she knew. And basically that’s when he found out. Afterwards they’re a bit awkward at the beginning, but have a very “interesting” night and they are tgt from that point on.

I read the novel, they became a couple and live happily after. i cant spoil more
