Description from your point of view (Pov):

Ever since I've come back to Korea and met my brother's friends for the first time, they've been so nice and caring . But this one friend of his really caught my eye when I met him... There was just something about him I really liked, but... He doesn't seem to like me very much... His name is...Lee Donghae . We always fight over things but in the end, I think I've fallen in love with Mr.Simple ? 

Plot:

Growing up with your older brother, Kangin, was great till things got tough . 

Your parents had passed away when you were quite young so you ended up moving in with your grandma . 

Although Kangin was only 16 at the time, he became very responsible of you . 

2 years later, Kangin graduated from High School and was excepted into SM Entertainment .

He ended up moving out and moving in with his soon to be group mates .

Even though you hardly saw him anymore after that; he'd come visit whenever he could .

Once you graduated from High school you were accepted into a college .

Full scholarship with all the perks . . . But sadly it was oversea's in America .

Which meant you wouldn't be able to see Kangin at all unless it was over a video chat . 

While Kangin was busy becoming famous in Korea, you were studying oversea's . 

He'd call often and video chat whenever he could .

After 3 full semesters was over, Kangin planned out for you to come visit him in Korea for the whole summer .

It'd been 3 years since you had seen your older brother and the first time you would get to meet s . 

When meeting everyone for the first time they had taken a liking to you . . . But not Lee Donghae . . .

Does he really hate you?

Or is Mr.Simple Hiding something ?
