One night around 2 am, you're walking down a dark street after a night out. Suddenly, you hear footsteps behind you.

Stealthily, you grab your keychain knife from your pocket, take a deep breath, close your eyes, and abruptly stop. Turning around, you scratch the intruder, only to discover Estan, your foe, holding his bloodied cheek.

He looks annoyed and asks, "Why did you do that?"

Arms crossed, you reply, "Why were you following me?"

Estan sighs and mumbles, "Can you invite me to your place? I have a problem."

Intrigued, you raise an eyebrow, "Problem with what?"

He sighs again, casting anxious glances at the street's windows. "With a mafia boss, I'll explain later," he mutters, waiting for your response.
