EX. I had probably seen the term OTP used before, but I didn't know what it meant until I saw this fanart in response to one of the statements from a Rioter about the upcoming release of a character and other characters. Apparently, my team's favorite ignored dragon, cuz we need a dragon camp but apparently the champ who can turn into a dragon doesn't count, was denied confirmation of a fan's belief that she and Jarvan IV were meant to be. As for me, I don't really have any OTPs involved in LoL. Do you have any OTP?
