"I always take care of V secretly."

They always mention how they are similar and have a lot of stuff in common, I get the conclusion that they are soulmates. They always think about eachother and various moments. They are more close than are showed to us.

"I want to become V's tree."

Taehyung always mentions how Namjoon understands him and vice-versa. Their bond is so beautiful, so well constructed in trust and understanding, they consider eachother pillars. They know they can always count on eachother. They act in public in various ways, funny, chaotic even odd, they are very comfortable in being the way they want.

"I think about RM when I'm sick."

They have a lot of creatively similarity. They both love ambiguish angsty in their songs, it's very different the way they pass on the lyrics but it matches perfectly.

"I'm number 1 at taking care of Namjoon hyung."

I see that Taehyung helped Namjoon a lot in being more relaxed with himself, and Namjoon helped Taehyung to be more confident with his mind.

I get emotional seeing such a beautiful relationship build by them, when you get to know more of the details it's impossible to not fall in love.
