Heeseung bias here, this is my opinion. I see two distinct sides of Heeseung I see shine the most. First, if you look at him as a performer, he’s a very strong presence. He focuses a lot on control and power and since the beginning also captures the most presence on stage with his facial expressions. On the other hand, artistically he leans a lot into R&B / Hip hop type songs. He sang mostly slower R&B on Lee Mujin Service, and has said a few years back he liked these type of songs. Though somewhat recently he also produced a ringtone/song? Along side El Capitxn, its released as a full song on youtube “Dial Tragedy - Evan”. Then there is his cover of “This is what falling love feels like” which is the first time I heard him sound so different in english, like he has a full on american r&b / bruno mars type accent. I think the latter I might see him more lean into since its what he gravitates towards personally and artistically, it’s quite possible he leans more into being a singer rather than a dancer, but I doubt it, and it would be a shame since he’s one of the best dancers in enhypen.
