Recently, a netizen posted on an online community a compilation of before-and-after photos of BTS leader RM.

It seemed many netizens were wondering what was causing the slight difference in his vibe since his debut. Apparently, RM had bulked up over the years and put on some muscle.

Previously, RM showed off a slim figure with long legs and arms, which made him look like a model. Now, RM gained muscles on his arms and thigh making him manlier than ever.

Many fans and netizens could not get over RM's unchanging good looks whether being skinny or muscular. Most netizens like both the skinny RM as well as the muscular RM, however, some still preferred the latter.
