Grateful for the connection he has with his fans, Zac Efron penned a sweet thank you to one young woman he met on Tuesday (January 14).

Accompanied by costars Michael B. Jordan and Miles Teller, the "That Awkward Moment" star stopped by Facebook headquarters for a Q&A.

There, he met Kirby Koo, who works in the sales development department. After their meeting, the 26-year-old actor posted a photo to Instagram of them sharing a hug with a heartfelt message.

In it, Zac writes, "@Curbiekoo, I have so much more I want to say. And I will- when I find the words. But I'll start here- When you stood up, with such strength, and sincerity and gave me perhaps the nicest compliment I've been paid...it meant so much more than that to me. @Facebook and online media in general, show only half the picture- sure people see me, but I never get to see them. Yesterday was the first time in a very long time that I was able to look into your eyes and remember why I do what I do- and will never stop. I needed that, more than you will ever know and just wanted to say thanks- face to face soon I hope. :)."

In response, the adoring fan replied, "Zac, I am so incredibly touched by your note. Meeting you was always the dream, but I never could have imagined that you would respond with such genuine kindness and literally open arms. The impact you and your talent have had on me and so many millions of others should never be underestimated. Beyond the actor, thank you for being such a warm, generous person and I'd be humbled to consider you a friend."
