~Eyes Outside My Window~ (YeonGyu)

Eyes Outside My Window. Every city has unsolved disappearances. Every crime scene leaves the police chasing shadows.

And every shadow seems to belong to one man.

For twenty-six-year-old Choi Yeonjun, taking a life is nothing more than another perfectly planned routine. Cold, intelligent, and frighteningly patient, he has spent years staying one step ahead of everyone. He feels no remorse, no fear, and no attachment. To him, people are simply names waiting to disappear.

Until one ordinary afternoon.

He sees nineteen-year-old Kang Beomgyu.

A carefree university student with an endless curiosity and a habit of poking his nose into places he shouldn't. Bright, stubborn, and impossible to ignore, Beomgyu is everything Yeonjun has never understood. Instead of becoming another forgotten face in the crowd, he lingers in Yeonjun's thoughts.

For the first time in his life, the predator can't stop thinking about someone.

The obsession grows stronger every day. Yeonjun finds himself watching from a distance, learning Beomgyu's routines, memorizing his smile, and questioning emotions he never believed existed. Is it love... or simply another dangerous obsession?

Meanwhile, strange disappearances continue to shake the city. As Beomgyu's curiosity pulls him closer to the truth, his protective older sister, Yeji, begins to notice that something isn't right. Someone always seems to be watching. Someone always seems to be just outside the window.

And the closer Beomgyu gets to uncovering the truth...

...the closer he gets to the monster who has already fallen hopelessly obsessed with him.

In a story where love and danger walk hand in hand, one question remains:

Can a heart that has never known humanity truly learn to love... or will it destroy the only person who ever made it beat differently?
