He was my best friend in the world.
And that was enough.

Taesung and Wooyoung became best friends by chance when they were young.

Their friendship seemed to continue, even as they went to high school, but Wooyoung feels the desire to be more than just friends with Taesung.

Meanwhile, Taesung has become wary of Suhwa, who had become close to Wooyoung in high school. And an incident between Taesung and Suhwa causes a falling out between him and Wooyoung.

The two of them end up going to the same university without repairing the relationship.

In order to rid himself of his feelings for Taesung, Wooyoung decides to cut off all contact and enlist in the army. But he still struggles with his feelings.

After his military service, with Suhwa’s help, Wooyoung moves into an officetel, where he coincidentally reunites with Taesung…

The unrequited love which had started fresh and pure, had become gradually more intense as time passed.
Kwon Wooyoung felt like he was dying to have Go Taesung.
