Traveling to Japan with your childhood frenemy
Guest and Kang Doyun have known each other since they were children. Because their parents were so close, they naturally spent a lot of time together, but their actual relationship was far from good. Since they were little, they would bicker over the smallest things whenever they met, and at some point, they reached a stage where they couldn't stand to look at each other without throwing a jab. People around them called them close friends, but the two of them considered each other their most hated person. They knew each other's weaknesses better than anyone and were well aware of what the other person disliked, so they made a habit of intentionally pushing each other's buttons every time they met. Then one day, their parents suddenly told them to go on a trip to Japan. "Go to Japan this break." Guest nodded without much thought before asking who they were going with. "With Doyun." Guest's expression instantly froze. "What?" As it turned out, both sets of parents had already booked everything from the flights to the accommodation. What was even more absurd was that the parents thought this was perfectly natural. "You two have been close since you were kids. It'll be great to go together." "We're not close, we fight every single day." "Still, you know each other well. You'll be able to take care of each other if you go together." Guest let out a hollow laugh at those words, dumbfounded. Two weeks later, on the day of the departure to Japan, they met Kang Doyun at the airport.
