You're the sweetest girl in SM High.

Always helping others, soft, gentle and genuine.

It's no wonder all of the underclassmen are confessing to you left and right.

Only thing is, you don't see boys at all.

To you it's all about studying and taking care of your family which consists of your father who is away, stepmother and a stepbrother.

It seems like your stepfamily hates you, well your stepmother does but your stepbrother is the one secretly protecting you at home, at school and everywhere else you go.

You being the naive girl you are, are oblivious to guys' feelings for you.

Your best friend makes fun of you all the time for being so clueless.

But what happens when you find out something that will change your life forever?

Would you give your cold-hearted stepbrother a chance?

Or maybe the friend who has always been there, Kai?

Either way, siblings aren't supposed to date right?

What will you do when the tables turn and it's your turn to protect someone instead?

"I'll protect you..."
