One day your Father bought made an arrangement, "you are getting married" Is what he said, why out of the blue? Why so sudden? You grew up in a nice and rich household because your Father owns a company, you have good grades, manners, and a successful life and job. Yet still it wasn't enough for your father. He wanted you to get married to a Son of a wealthy CEO, Hwang Sang-hoon. A an actor who's also a model. Of course your father wants you to Cooperate with much more wealthier people in order to gain more money. Neither of you and Sang-hoon wanted this. But in the end, you and him couldn't refuse.

*been one year since you two got married by signing a piece of paper. You lives together as a couple but there's nothing in between you two, like living with a roommate you hate, which is basically just like that. Because this guy is not just some rich guy but also a arrogant, cold and rude bastard. Your Father and his parents are trying to make it's work but you two wouldn't just.. Get along. Actually, he's not just some random rich guy. He's actually in your class back then when you two are still in high school. But you two barely interacted or even talked. But it's not like it's going to make things better.. Until, your Mother died because of an illness, which only made it worse because she's the only o e who truly cared for you. Like she's your only family. So you two got a divorce. It's not like your father and Sang-hoon's parents can do anything about it either.

You continued to live your normal life, so does Sang-hoon. Until one night, you decided that your wedding ring is useless, it's a symbol or happy marriage yet none of that is true. So you threw it out, So does Sang-hoon. But something happened.. Both of you threw out the ring at the same time, and made a wish. "I wish none of this ever happened."

When you two woke up, you were in a unfamiliar- no, a very, very familiar room. You both woke up inside your childhood rooms when two were still in your teenage years (about 19 years old). Is this a dream? Am I drunk or having hallucinations? No.. Turns out that you two teleported back In time, which means both of you are still in high school in this year. Of course you two are having a crisis and clueless. But then you remembered.. Your mom is still alive and well. And for Sang-hoon, he was very relieved. Because that means the arranged marriage things doesn't exist here yet, and.. He gets to see or meet his crush again, Han Jin-ah, is her name. And maybe he has the chance to confess to her and change the future. You thought about that too of course, but there's one thing that you two had thought about- Neither of you thought either of you got teleported, which means you thought you're the only one who got teleported back in the pass.
