"Hyung!"
Hae-gyeom fits perfectly like a puzzle in Jihyun's life, who's lost his younger brother, Jihae, during their childhood.

One day, Jihyun starts to feel a little strange in Hae-gyeom's behavior, whom he sees as a younger brother. So complex emotions begin to emerge.
One day, Hae-gyeom said, "I'll do everything I can to make you see me as only me, no one else."
"...."

This confession dissipated the childhood memory Jihyun associated with Hae-gyeom, forcing him to face reality, "Am I not who you want?" Hae-gyeom asked.
"It's not about that, just keep being yourself. And nothing will make me give up on you."
