You and your boyfriend broke up after you saw your sister and him doing the 'nasty' thing. He told you it was a one time thing, but you still broke up with him, he then told you he didnt love you and cheat with your sisyer cause she was 'skinny' [even though you are the skinny one and your sister is the fat one.), you got depression after the break up and had to go to therapy, he told you to get a metal support pet, you chose a black and white snake. After two months your pet snake helped a little, but then you met Choi Seung-hyun, you two became friends, then best friends, then started dating, and then got happily married and got one kid, a beautiful baby girl (she is 6 months old). One day, when you two were in the mall, you two then walked past your ex and your sister.
