Summary
Ever since Serizawa could remember, people had been afraid of him. Whether it was kids at school calling him creepy, or well meaning relatives who backed away when he asked for a hug. He’d understood very early that touch was a luxury.
Suzuki’s hesitation had not been out of fear, but a clinical sense of duty and nothing more. He certainly never gave Serizawa a hug. Serizawa had come to accept this loneliness, though he wished he could change it. Reigen had no such qualms about touching him. He was happy to rough him up a little, and that felt freeing, especially when they began to date.

Summary
It had surprised Serizawa, learning Reigen was such a private person. After all, when he first met the man he offered him a job without question. Well, maybe a few questions. But he’d seemed so outgoing and self assured; the kind of person who had lots of friends.

There's something wrong with Reigen Arataka.
He doesn't have whatever it is that other people have that makes them care about each other the way they're supposed to. Perhaps that's why he became a con artist - he's already a fraud who doesn't care about others.
Or, everyone's favorite pathological liar trying to figure out where lying to other people ends and lying to himself begins.
