Andrey Rublev and Daniil Medvedev played their first match vs. each other when they were kindergarteners

We're the two best friends that anyone could have!Andrey Rublev and Daniil Medvedev are opening up on their longtime friendship in ways never before seen in a new video feature by the ATP Tour.

The biggest takeaway from the new clip, which the men's circuit heralded this week as the video "you've all been waiting for"? The tear-stained memory (of course) of the first time that the two ever played.

The pair's friendship began when both were kindergarteners, as Rublev recalled playing Medvedev in the quarterfinals of a local Russian tournament when they were "5 or 6 years old."

"I see the guy, a sleeveless T-shirt, only one racquet, and I say, 'What is this? He's in quarterfinal with me? No chance I'm going to lose to him,'" Rublev recalled.

Emotions, as expected, ran high in a match that Rublev eventually won.

"I remember that he was going crazy after every lost point, just like me," Medvedev said. "When I saw it, I knew I acted like this, but I was like, 'Who is this guy? What's wrong with him?' That was pretty funny."

"I lost the second set and I remember I was crying in the bathroom to my mom, 'What is this? I cannot beat this guy! How is it possible?' Rublev added. "Since then, we were like, 'We're going to be best friends!'"

The duo has grown up to be two of the current stars in men's tennis, and despite a 7-2 record in favor of Medvedev, their love for each other has endured—so much so that Rublev has the "privilege" of being the godfather of Medvedev's daughter Alisa.

"The best quality of Andrey is his kindness, I would say," Medvedev said, telling the camera that his one wish for his friend is that he be happier. "I think everyone knows that he does a lot of charity, probably signs the most autographs out of all the players."

In just three minutes, fans will laugh, cry, and come away with a new appreciation for a connection that's not just one of the most genuine in top-level sports, but also in life.

"I think it doesn't matter what's going to happen now, we have each other's back already forever," Rublev said. "You're in my heart."

Medvedev, ever the jokester, countered: "Forever? I don't know! But for some time, yes."
