ARMYs are still emotional after BTS's first member, the group's eldest brother Jin, began his military service. Two days ago, BTS members sent their eldest brother Jin off to enlist and that moment made them sob.

While ARMYs are having mixed feelings, so are the BTS members, which was captured in the group's newly released Bangtan Bomb. In the video sharing BTS's interesting moments before enlistment, ARMYs quickly discovered a cute fact when the members took pictures with Jin.

It is the way they pose that makes ARMYs think of each member's family relationship:

The BTS members have formed a brotherhood for over 10 years as they overcome the trials and tribulations of debuting under a small agency. Now, BTS creates a new path for K-Pop artists as they rise to international superstardom.

Their more than a decade of experience in this friendship has created a close family bond between the members. This is evident in their caring and loving actions towards each other. For Jin's enlistment ceremony, the members gathered to see their brother off, and BTS' V even flew back to Korea overnight from his international schedule so as not to miss the ceremony.

On the 13th of this month, the members accompanied Jin when he arrived at the military training center and said goodbye to him by rubbing his short hair. They even refused Jin's request when he said they should get in the car so they wouldn't get cold and linger until Jin had joined the ranks of the new soldiers.

Along with that, the members also took turns taking photos with Jin to preserve once-in-a-lifetime memories. But also thanks to these moments, fans noticed that the members' different ways of taking photos show their posing characteristics differently when they have different siblings.

One fan shared on an online community this discovery with the topic: "I have an Oppa too (older brother) and he always poses the same way as V and RM when we take photos together, lolol."

Specifically, every BTS member has at least one sibling, and their poses humorously reflect their role among their siblings. While j-hope, who has only one sister in the group, took a picture with Jin in a very close way. j-hope's tight hug in his photo with Jin is top notch "little brother" behavior.

Meanwhile, Jin, Jungkook, and SUGA all have older brothers. With Jin, they pose humorously like a younger brother who is asked to stand still to take a picture with his brother. Although they looked awkward and difficult when posing for photos, it was actually just SUGA and Jungkook's expression when they were confused and emotional when sending Jin off.

In addition, in it, V has a brother and a sister, and RM has a younger sister, and both are very protective of their younger siblings. Although they are both Jin's dongsaengs, RM and V tilted their heads towards him with the affection of a protective, loving, and strict older brother.

Along with V, Jimin also has a younger brother! A photo between Jimin, V, and Jin is the adorable combination of an adorable brother and a cute little brother as they make faces and take many pictures together.

OP (original poster) who pointed out the family dynamic. Under this OP's analysis, netizens could not agree more, finding BTS's poses very cute and adorable:

- I have a Hyung too, this is freakin hilarious

- It's funny cause V also has a younger brother and he's in both photos - the one for younger sister and younger brother, lol

- I laughed so hard at the photo showing the members who have hyungs (older brothers)

- OP, I'm shocked that you take photos with your Oppa lol

- It's more fascinating that fans found this pattern lols.I was very happy to see all seven together. It's going to be an adjustment for the six staying behind. And we have to go through this six more times! Good luck to Seokjin - we love you. 

- ARMY being ARMY. Fans must have stared at the photos and watched the videos hundreds of times. It is what it is. I can't even imagine how JK is feeling, as he is obviously Jin's baby bro among them all, saying they raised each other in multiple occasions.

- Army are body language experts. That's so cool they noticed this and it's spot on! The guys are truly a family yet they do have their own families who they love and who love them. From what they've said, even some of the parents are besties lol It's a beautiful bangtan family.
