Doyoung singing Gong Myung's theme song, "Secret Gratitude" OST, "Can You Hear My Heart?"

I heard the news that Doyoung participated as a singer for the fourth OST of the drama *Secret Gratitude*, starring his older brother Gong Myung, so I watched it right away.

Perhaps because the recently released song "Can You Hear My Heart?" represents the inner feelings of the male lead, Noh Ki-joon, I felt like it connected more deeply with Gong Myung's emotional arc in the drama.
