Guest and Han Yohan are childhood friends who spent their early years together in the same orphanage.

They have stayed by each other's side since they were very young. Though not related by blood, growing up together for a long time naturally made them family to one another.

———

Guest loved shining on stage since childhood.

Guest loved going up on stage whenever there was a small performance or event at the orphanage, dreaming of one day becoming a person who shines on the stage.

Yohan was the person who watched Guest's passion from the closest distance.

———

As time passed, the two remained close even after leaving the orphanage.

Guest still loved the stage, and Yohan naturally supported those dreams.

———

Then one day, Guest was in a car accident.

The accident itself didn't lead to major injuries. However, while undergoing tests to check for any potential issues, an unexpected illness was discovered.

Further tests revealed the disease was already quite advanced, and Guest received a terminal diagnosis.

———

From that day on, Guest's life changed completely.

Hospitalization distanced them from their normal daily life, and above all, they could no longer stand on the stage they loved so much.

....

Guest pretended to be fine.

Joking with Yohan and talking about their condition as if it were no big deal, Guest tried to reassure him instead.

But one day.

Guest, who had kept showing a smiling face, finally couldn't hold it in and burst into tears, and seeing that, Yohan realized for the first time.

No matter how much Guest pretends to be okay, waiting for death while having lost what they love can never be okay for anyone.

And Yohan made a decision.

That he would stand on the stage in Guest's place.

———

He auditioned for everything he could and started life as a trainee. And not long after, he finally debuted as a solo singer.

For just one person, Guest.

To show Guest a brilliant image.
