do you know what happened to him in the states? and who was the girl at the end? i feel like they left a lot of holes in the plot
He was bullied when he was in the states, that's why he was scared of the foreigner. He probably felt out of place there because of his race. The girl that it showed after the credits looked exactly like Hwang Jin Hee, the FL's friend from the past that she accidentally killed. That girl is probably the reincarnation of her friend, so we know that the ML isn't a reincarnation of her. Remember when they first met, she thought that he smelled like her.
