Taeyeon is the Princess and Angel of Kim Family because she was the youngest child. Her father was Kim Junsu while her mother was Kim Min Seol. Mr. Kim is the richest men in Seoul country and has own his company.

Taeyeon have 4 brother who always protect her especially Heechul. He always by her side, didn't left her alone.

Her brother was Heechul (the oldest child), Jaejoong, Kai and Suho.

Taeyeon's brother Kai and Suho are always but even they always like that, they always protect her from any kind of danger when their older brother was nor around.

While the older brother, Heechul and Jaejoong are, also, a very overwhelming brother to protect their siblings and will do anything to make them happy.

What would have passed if someone came in Taeyeon's life and that made her brother Heechul are very over protective towards her and didn't let them alone. And what if the person was a girl? Can they let her with the girl?
