Netizens were shocked at how thin BTS member Jin's legs looked in his latest Instagram post.

On March 11, one netizen took to an online community to create a post titled, "What is up with BTS Jin's legs...?" Here, the netizen included a photo Jin had recently posted on his personal Instagram and wrote, "I got so shocked after seeing [his] Instagram...Was he always this thin...? I did a double take."

In the photo, Jin is seeing showing off his special character cap in a casual white T-shirt, a navy sweater, and a pair of jeans ripped at the knees. While nothing seemed out of ordinary at first, netizens looked closer at the ripped jeans and noticed that Jin's legs were actually much thinner than how his jeans made them seem at a simple glance.

In response, some netizens commented:

"He really is thin. His height is 179 cm but his weight is 61 kg..."

"It's true that he's super thin. Park Jimin is really frail and has a short height but Jin, who is taller than Jimin, weighs less than him. His shoulder bones do everything because they're so broad he doesn't seem [thin]."

"He lost a lot of weight TTT Hearing him, I don't think he's on a diet, but he has a lot of activities so it's likely he didn't have an appetite and naturally lost weight."

"Kim Sukjin's shoulders are extra [wide] so he doesn't have the thin image, but if you think about his weight, he's crazy thin. Please eat like the past 'Eat Jin'...."

"I was shocked after seeing his weight, but just looking at his frame he doesn't look that thin."

"I didn't know he was on the thin side because of his shoulders. but looking at the pictures he is pretty thin. But male idols are usually like that."

"For health, he could gain some more weight."

"His legs are so thin...I'm so jealous TT."

"If you look at him, he just looks thin. RM just has a chubbier face, but if you look at his overall shot he is also thin."
