Taeyong needs a girlfriend.............actually scratch that.

He has to get a girlfriend–if he doesn't, his parents are going to roast him. 

Somehow the idea that a man must get a suitable partner by the age of twenty (and then get married as soon as possible) has been etched in their heads, apparently, ever since he was born.

However something is preventing this from happening.

The girls that he likes are never accepted by his parents (who are by the way very important to him), because they want a girl who has the characteristics that never seem to catch his eye: a good girl.

A good girl meaning that she can cook, take care of children, clean the house, is capable of taking care of her husband, responsible, doesn't party, doesn't drink, doesn't smoke...to put it shortly: mature and knowledgeable.

While Taeyong just wants someone that he likes, and frankly good and mature girls doesn't seem to be a part of that.

To stop his parents' nagging, he gets a fake girlfriend; she's a girl from his school, and whom he didn't know until he noticed how 'good' she was. And whilst this is happening, he dates another girl in which he really likes.

But it only takes some time, before things gets complicated.

Really complicated.
