Netizens on online communities are having a serious case of if-you're-tall-and-good-looking-then-you're-oppa syndrome, after seeing photos comparing Jisung standing next to Red Velvet's Irene during his S.M.ROOKIES days and him standing next to Irene after debuting in NCT Dream. 

In the first photo below of a polaroid showing S.M.ROOKIES members Irene, Jisung, and Haechan posing together, Jisung is tiny with Irene's hand on his shoulder. But in recently captured screen shots of Jisung standing behind Irene during 'M! Countdown', he's shot past all of the Red Velvet members except maybe the group's tallest, Joy. Being 14 years old internationally, you can bet Jisung is still definitely growing.

Wondering how much taller Jisung will grow, netizens wrote, "If he grows over 180cm with that face, it would be daebak... he's about 170cm now they say...", "If you're tall and good looking than you're oppa!!", "It must be amazing for Irene too kekekeke. Seeing a kid who used to be a head shorter than her grow a head taller kekekeke", and more.
