this is from a Japanese fan’s Twitter text-photo-post that a Chinese fan has translated; in to English by me. Not exactly unusual account from a staff to a friend, take with a grain of salt, but most things seems reasonably believable /and oh so very precious;;/
“K-kun also said, when Changmin looks at Yunho, it’s such a gentle gaze.”

The fan’s words:
“Even though I have some worries, but I still want to write about some moments that made me truly believe in their bond.
Because this is told from a friend, this could be said to be written from my own feelings, I don’t know if this will bring trouble to my friends, I’m a bit cowardly and a little afraid.
(I obtained permission from my friend to write this. If this ever make any problems, I will make this a private note) *t/n this post was made on her blog and then spread through twitter via long text post picture
Anyways, I will try my best to write in a way that won’t trouble my friend.
My friend, K-kun, from sometime ago, has had chance of numerous encounters with Yunho and Changmin.
But K-kun’s knowledge of Tohoshinki is only limited to knowing who is who. He doesn’t know that the two are very close. And he doesn’t know I have a fujoshi side www
K-kun said, I wonder what kind of relationship those two have.
After hearing this I was a bit confused, I thought, “Eh? Is their relationship exposed.”
But then after talking to K-kun about this for some time, I understood that he did not mean it in any shipping ways at all.
K-kun told me these moments between the two.
They don’t talk very often, but they always sit together. When someone they don’t know very well, like K-kun, give a drink to Yunho, Yunho wouldn’t drink it just then. And then at this time, Changmin would very naturally out of instinct take the drink, pour it in a cup, or open the cap and give it to Yunho, and then Yunho drinks it.
Sometimes water drips from the cup; Changmin would clean it immediately.
Sometimes Yunho would be coughing; Changmin would pat his back and give him some water.
Sometimes after sitting so long and suddenly getting up Yunho would feel a bit dizzy; Changmin would hold out his hand and help Yunho immediately.
