TXT's Taehyun singing the OST for the Japanese drama Stairway to Heaven

Tomorrow X Together's Taehyun remade the popular Korean drama Stairway to Heaven.

News has spread that they sang "Aitai," the OST for the Japanese drama *Tenkoku no Kaidan*!

I'm looking forward to it since it's being released exclusively on Amazon Music from June 4th to July 3rd!
