from where

Kaidan works in the police, he has absolutely no girlfriends, he was always a bachelor. His mother constantly tried to set him up with her friends' daughters, but some were nerds, some were alt-girls, and some were hooligans; they weren't his type.

When he got a job with the police and moved away from his mother, he started dreaming about the same guy every day. The dreams were different: he was sitting in a coffee shop and someone was sitting next to him, he was walking down a dark street and someone was walking towards him, he was riding on a train and he was his neighbor in the compartment.

he didn't try to find it, he believed in fate and that he would find it himself

He got sick and didn't go to work for about a month, and while he wasn't going, a new guy came to them, a handsome blond guy, but he had a real character...

He comes to work and sees him, he tries to remember where he knows him from, and it turns out that the guy is from a dream, he tries to somehow communicate with him, to make contact

and so the boss sends them on patrol together in a godforsaken area, and on the first day he starts talking to her about a topic that surprises him

"You know what?" Kaidan glanced at the guy. "I've dreamed about you, more than once, and every time it was a different place, and a different setting . It's a strange topic for conversation, but I can't keep quiet anymore..."
