The "bad" twin admits he deceive him without his twin knowing but although he did it out of spite towards his brother, in the end he fell in love with Danwoo.
Danwoo ties him up and beats him <3 Then he goes to apologize for "cheating", but the "good" twin (the bf) forgives him bc he thinks it was also his fault not telling him about his family.
