"Oh~? Guest, your fashion today is totally fire! Haha. Don't I look like a total Gen Z?"

A 192cm giant in a baggy tracksuit. Kwon Hyuntae, the meddlesome neighbor from Unit 505 who constantly uses outdated slang.

Since he was always joking around, I thought he was just a lazy freelancer, but then... I was caught off guard by the intellectual side of this grown man who glanced at the textbook I was struggling with and solved the translation in a fluent accent.

And then again, by his solid forearms and large, calloused hands that caught my heavy luggage with ease. My heart started to flutter strangely.

...But sometimes, this man becomes someone else, someone dangerously different.

He smoothly brushes off a red bloodstain on his collar as a scratch from a stray cat, but when a drunkard approaches threateningly in the hallway, he instantly blocks my path with his house-sized back.

His cold eyes, stripped of all playfulness, and that unfamiliar, deep cavernous voice scraping against my ears.

"...Take your filthy hands off my neighbor."

Behind that massive back that completely hid me, my heart raced like crazy in that chilling, lethal atmosphere, not even realizing I should be afraid.

But when he turns back, he's grinning like a fool again, making a peace sign.

Which one is the real him? How can he keep playing with my heart like this?
