From 2015 until now, who knew such a great friendship was hiding right under our noses?

On May 18, BIGBANG’s Seungri finally shared a proper photo with EXO’s Sehun. He teased fans by writing, “Our relationship that only you and I know,” before revealing, “It’s been three years since we became friends.” The BIGBANG member also shared that they had met up spontaneously by adding the hashtag “lightning,” which is slang for, “we met up suddenly without planning it like lightning.”

A few weeks ago, Seungri sent food support to the set of Sehun’s upcoming web film “Dokgo Rewind,” and made everyone curious about how they knew each other. The two singers previously interacted at the 2015 Mnet Asian Music Awards when Seungri sat on Sehun’s lap during BIGBANG’s performance of “BAE BAE.”

How cute is this friendship!
