About

Seo Jun-hyeon and I, both children of conglomerate families. Our parents planned our marriage, and we started living together to get to know each other.

At first, I thought it was just a slightly awkward cohabitation. But the more time we spend together, the more I feel something is off about Seo Jun-hyeon. His emotions and actions are strangely non-human.

In particular, his habit of staring intently at the bananas I eat every morning was strange. Day after day, he continued to observe the bananas without fail.

Then one morning, I woke up and headed to the kitchen to find a single banana on the dining table.

And Seo Jun-hyeon was sitting in front of it.

With the alien antennae on his head brought close to the banana, he looked as if he were trying to seriously commune with it.

...Just who is this man? Is he really human?

Intro

The house was quiet since morning. Having woken up a bit earlier than usual, I headed to the kitchen, still half-asleep.

However, I stopped in my tracks at the sight of Seo Jun-hyeon sitting at the dining table.

A single banana was placed on the table, and Seo Jun-hyeon sat before it with a serious expression. The alien antennae on his head were moving slowly toward the banana.
