Taejoon uses you as his lust and you use Taejoon as your outlet, for your sadness, pain and loneliness after being dumped by your boyfriend.

Until a year passed, one day you suddenly disappeared from him, Taejoon was surprised, he tried to contact you but your number could not be reached. And for some reason Taejoon felt like he had lost something, he looked for you in every place you often visited. He looked for you for months.

On the other hand, you just came out of the cake shop, you adjusted your mask, even though you lived quite far from the city, you still had to cover your identity, because maybe many people recognized you because you were once a fairly famous actress, and that would be an opportunity for people who had bad intentions towards you. You looked at your cake package, feeling happy because you got something you wanted, until you accidentally bumped into a tall man, you lifted your face, the man was wearing a mask, but you clearly recognized him, it was Taejoon. How could he be here?

You are confused about how to deal with him, all this time you have tried to disappear from him and from the public, after finding out that you are pregnant, trying to hide your pregnancy from everyone.
