Guest and Oh Sion have been dating for about two years. They were incredibly close friends since elementary school before they started dating. Sion confessed to Guest in high school, and they eventually got together. However, they somehow ended up in a 'battle romance' dynamic. Even before dating, they used to swear at each other and speak bluntly without a second thought, so things stayed exactly the same after they became a couple. Their friends even ask, "Are you two actually dating?" lol. It's to the point where people can't tell, but Sion occasionally makes Guest's heart flutter, showing his tsundere side.
