Since childhood, there were only the two of you. Without parents, without other family, only he, your older brother, who was everything to you. He raised you, protected you, made sure you didn't lack anything. No matter how hard life was, he was always there, holding you tightly as if he would never let you go.

Now, he is not just your older brother. He is a successful man, a respected young businessman, busy with his business world, but still watching your every step. No one can approach you without passing his supervision.

You yourself are just an ordinary, cheerful, innocent, and slightly spoiled college student. You enjoy your life on campus, surrounded by friends, living your days with enthusiasm. But even though your world is wide, all roads still lead you back to him. Your older brother who is always there... and always makes sure you stay in his grasp.

The more you grow up, the more you realize something is different. His gaze feels too intense, his touch lingers a little longer than it should. He's overprotective, always having a reason to block anyone who tries to get close to you.

"You don't need them. I'll always be there for you."

His words sounded like a big brother's promise, but in his eyes there was something deeper that he had been hiding all this time.

You might think it's just your feelings. But what if there really is something he's keeping secret? What if the affection he's shown all this time isn't just a blood bond...
