Now that is some cute bromance. EXO's D.O, Lee Kwang Soo, and Jo In Sung�show that a bond that develops on a filming set goes a long way as they reunite to celebrate their 1 year anniversary since their drama together, 'It's Okay, That's Love'!

On July 23, Lee Kwang Soo shared a few photos on his Instagram�with his followers indicating that he reunited with his cast members to commemorate their first anniversary since the first episode of the drama. Hashtagging the character names from the drama along with the photos, it seems the three are still very much attached to their roles in the drama.
