My Shadow Guard Is the Tragic Male Supporting Character Who Loves Me but Can Never Have Me

My bodyguard is a tragic second male lead whose love goes unreturned.

After the heroine abandons him, he goes to the fighting arena every day, hoping to die.

I leap from the attic: "This princess got hungry and accidentally fell off the building."

He scrambles up from the ground, eyes wide with horror, catches me, and resigns himself to preparing my dinner.

At the wedding of the male and female leads, he storms into the enemy kingdom alone, shouting that he'll die alongside its emperor.

I peek out from the enemy ranks: "You're here? They said they're going to feed me to the wolves in a little while."

He stares at me, wide-eyed. "Princess, what are you doing here?"

The male lead sneers, pointing between me and the heroine, and asks him, "Do you want your little princess, or my empress?"

He grits his teeth. "Give me back the princess!"
