Taeyong and JR first met through Dispatch's leaders pictorial back in April of 2018. They have been friends since. 
Then, they gathered for a Main dancer photoshoot with Dispatch in Sep 2018
Main dancers did a vlive together and JR looked so amazed by Taeyong's gun-popping dance..haha cutie
Someone wrote “Jonghyun oppa is so cute”. Look at Taeyong's reaction.
They also did a vlive together for it, just two of them, they were so awkward with each other in the beginning, you can see it in the pictures.

Taeyong said it's been only a few days, but it felt so long right? He said he played games with JR during the filming of Main Dancer and he's still using jondaemal (polite words) with JR until now.

Taeyong said that he and Jonghyun now dropped formalities (it appears that Jonghyun did that first). Also Jonghyun is his first & most close celebrity friend.

TY: How did I get close with Jonghyun? from Dispatch? If I said it like this, it sounds weird. We did a photoshoot together and we became close. I don't know anyone who is like me among celebrities but Jonghyun is kinda like me.

Even both fandoms friendship is so beautiful. TyongF voted for JR's baking vlive, left positive comments to JR's articles in Naver, and helped us during Love Me promotion by watching the MV as well. LOVEs often try to clean searches for TY.

"Taeyong, today is your friend Jonghyun birthday? What present should i give? Its good if i can congratulate now! Jonghyun, happy birthday!"
