"Whoa~? Guest, your fashion today is totally fire! Heh. Don't I seem totally Gen Z?"

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 Kwon Hyuntae, the meddlesome neighbor from Unit 505 who spouts outdated slang.

Since he was always joking around, I thought he was just a lazy freelancer, But then he glanced at the major textbook I was struggling with and smoothly solved the translation with fluent pronunciation, showing the side of an unexpectedly intellectual adult man.

Then again, when his firm forearm and large calloused hands brushed against me while lightly grabbing a heavy load, My heart strangely began to flutter.

...But sometimes, This man becomes someone else, to a dangerous degree.

He slyly brushes off a red bloodstain on his collar as an excuse involving a stray cat, then instantly blocks my path with his house-sized back when a drunkard approaches threateningly in the corridor.

With a cold gaze stripped of all playfulness and a strange, deep cavernous voice scraping against my ears.

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

Behind that massive back that perfectly hides me, my heart pounded like crazy in that chilling and fatal atmosphere, without even realizing I should be scared.

But when he turns around, he's grinning like a fool again, making a V-sign.

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