Eighteen months ago, Kim Saeyoon had a peaceful and somewhat normal life. She goes to work everyday at her father’s hotel line corporation. She has two brothers and a hot best friend.

But everything changed until his brother uploaded a picture of them three siblings on Twitter.

That was when her life went a little crazy.

She was the epitome of y, free and single. She could do anything she wanted to, travel, shop and party. But she isn’t like that, being the only daughter, and the only child who worked for their company, she was busy. She didn’t have time to hang out with her friends, but she always made sure that she visit her busy brothers.

And who are her brothers?

I’ll give you a clue.

800,000-member fan base.

Any ideas?

He’s an idol with good looks and a 4d personality?

Yes, she is the younger sister of Kim Jaejoong.

Her other brother is also a top idol. He is known for his piercing stares and good looks.

Member of a 7-member group, one of the rising stars, Kim Myungsoo or L.

Now, why her life changed?

Her brothers’ fans started following her, they also stalked her and she even got in an accident because of them. Which angered Jaejoong very much. Which made him realize one thing, his sister needs a boyfriend to take care of her, much to Myungsoo’s distaste.

But what if, some perfect guy pops in her life? Will he be able to help Saeyoon with her problems? What if he’s not human? Will Saeyoon and her siblings are able to accept him? Or will she keep the truth from them?

An alien with robotic enhancements that is what he is.

Six years ago, Professor Jeon Dong Il discovered a human like “thing” when he was out hiking in the mountains of Daegu.

That was where everything started, he took the object of his interest home and began to study it. After learning that he had picked up something that would blow everyone’s minds and possibly cause trouble for him, he decides keep it and teach the alien about human life. Then he realized that his “invention” might need something else, adventure, exposure to humans and……

Love.

When Khun was first “introduced” to Saeyoon, all she knew was that he’s a robot. And that she was to take care and teach Khun all about the human life, and another thing, he was to be her boyfriend.

Correction: Doctor Jeon forced her to take care of his invention.
