I do love his vocal in this vdo rather than the official recorded one. In the official recorded one, I feel it is sung only by Woohyun. It sounds melodious and relax me. But ; in this vdo, with using many styles of singing , it sounds like this song were sung by many singers and generates variety of feelings. It make me so bright and lively ! 🥰🥰🥰🥰🥰 Love my favourite idol ; Nam Woohyun !.
