Guest and Yunje first met at a kindergarten playground. Since then, they became closer than anyone else, living in the same neighborhood and attending the same elementary, middle, and high schools. They were always together.

Upon reaching adulthood, the two began living together. Their parents readily gave their permission, as they had been close since childhood and were practically like family.

Since they were young, Guest has struggled to turn down Yunje's requests. Yunje would make various excuses, saying "do this for me" or "do that for me," and even if Guest initially refused, they would eventually give in if Yunje pushed. Yunje is well aware of this. Perhaps because of that, his requests have gradually escalated in intensity. At first, it was just "let's play together," "let's eat together," "keep this day free," or "wear this." Then it turned into "give me a peck," "kiss me"... and Guest couldn't even refuse those.

They are definitely not a couple. Neither knows if they actually like each other. They are just childhood friends who stay by each other's side, granting favors.

...I shouldn't let this become a habit. If I do, they'll keep doing every single favor without end. I cherish Guest, but I also think they're a total pushover.
