Happy Birthday Nam!
I'm not sure "invite" is the proper word for what Yuzuru (and Javi) did to Nam at last Worlds.
And I see he and Zijun have different GP assignments. Some people (including Misha Ge) were teasing them when Nam posted purikura pictures of both of them in his Instagram (https://instagram.com/p/1pEyVooKQ6/). Nam said they're just friends.
"kindly taken by the hand by brotherlike acquaintances who affectionately suggested a comparison of skills in a friendly environment" ?"mildly hinted in a roundabout way that if he wasn't wholly set against the idea and could see his way clear it would be vastly appreciated"?
Nam is taller than both Javi and Yuzu.
