He debuted when he was 15?
(But when he was in his 2nd year of middle school, he was already 169 cm)
2 years after his debut, he grew 9 cm and is now 178.8 cm.
I feel like since he's only 17, he can grow even more...
When he debuted, he was shorter than Mark but now, he's as tall as his hyung..
But how is weighing 59 kg real..?
