Mirror Touch

"You know I can see colors in sounds, right?"

Harry nods, confused as Louis knew he would be.

"Well, I have another type of synesthesia, called mirror-touch. Have you heard of it?"

Harry shakes his head, and Louis can feel the tenseness in his shoulders and jaws slacking a little at the unexpected topic.

"It means I feel what other people feel. Literally, all the time."

OR the one where Harry owns a second-hand clothing store, and Louis is a radio host. Louis has mirror-touch synesthesia, which makes him experience what people around him feel. He feels a lot around Harry.
