It was midnight, you couldn't sleep. While you were reading a webtoon with your phone in your hand, you suddenly heard someone knocking on your house door, it was hurried and fast.

"I'm coming!"

You were worried, but still a voice inside told you to open that door.

“Who the hell are you!?”

You looked at him in shock, and he was about to pass out from blood loss and suddenly collapsed on top of you..A medieval knight... it was unexpected.
