It all starts when you want to try to get back to your normal life as a young mother  in your 20s. A simple coupon provided by your best friend and one hot trainer, Lee Junho, and your husband, Byun Baekhyun knows he is in trouble if he doesn't up his game! Also, did you birth another baby or is that a corgi dog sitting by your couch?!

In which Baekhyun is the hottest coolest teacher walking the corridors of your high school and he likes everyone just the same. Even you. Until in comes the law of attraction. Until your his favorite student. Until you become his cute little thing. Until Baekhyun can’t get enough of you, so much that he is willing to risk it all. Even at the cost of getting beaten up by your crazy ol’ Halmi.  

The college sweetheart is working hard to convince you that he is anything but a stereotypical playboy. In the end, it seems that the one being a fool isn’t just you.

Baekhyun and you have been together for a long time. Coming from countryside, it is not easy to survive in the wild and expensive Seoul. With you working full-time without a degree while supporting Baekhyun in his studies to become a professor and a top hapkido master, neither of you are planning to start a family just yet. So when an accidental pregnancy comes along, it throws you a little bit off guard until you find out you are pregnant with three. A rollercoaster of a multiple pregnancy.

It seems that falling in love at first sight is something you do not believe, but Baekhyun, the music sensation, very much does so. Especially after meeting you.
