Seonghwa's life has never been easy. Growing up in a poor family his childhood is not much but bad memories. Getting into adulthood, as much he hoped, didn't change anything. Still struggling financially, being anxious and depressed and well mostly alone is not the best thing. And that's when he meets his freshly moved in next door neighbour Kim Hongjoong. The total opposite of him. The man leaves him stunned the first time when they meet and never fails to make him surprised. Getting closer to each other wasn't his plan but he regrets nothing. Falling in love wasn't his plan either. Yeah now that he doesn't really like.
