te way they have of interacting with each other is soo unique and special, it's reserved only for each other and different from the other members.
Ofc we don't know how they act bts, but as fan following them for years, one can see jungwoo is the type to initiate skinship with his members and friends, sometimes just as form of affection or to joke around. He's one of the nct members with most kissing/flirty compilations for all the times he's done so lol but with doyoung, he changes. Suddenly he's too conscious and aware of their public setting, and shies away from getting too close to him. It's been very evident these past years, especially because during debut jungwoo was his usual flirty self with doyoung too (everyone remembers the "I want a kiss from hyung" moment). And doyoung is very aware of that too. Everytime they are set up next to e/o, he's the one looking to keep the visual contact and close the distance. It's like he wants to tease jungwoo, in a "I enjoy watching you get nervous over me" way. All of that leads me to ask whats going on behind cameras for them to act that way. Is jungwoo's shy reaction to doyoung a sort of inside joke? Why is doyoung's boldness reserved only for jungwoo? And why does he get so hyper conscious for something so normal for idols like looking at your bandmate in the eyes??
I can't have the answers but i do know that with each year that passes, my belief in their very special dynamic and relationship grows. There's no other way to see it.
