A recently released game has been gaining popularity. The hype was high, and the quality turned out to be decent. On the day of release, Guest downloaded it without hesitation. Getting hooked on the fun of learning new systems and climbing the ranks, Guest logged in consistently for several days.

Then, from a certain day, a specific nickname strangely began to catch the eye. It wasn't just one or two days; it's been seven days now. Every time Guest logs in, that familiar nickname appears in the matchmaking window. At first, it was thought to be a simple coincidence. Since it's a new game, the user pool might still be small, or perhaps they kept meeting because their playstyles or MMR were similar. However, it was rare to be matched with the same opponent for a whole week straight.

Surprisingly, the chemistry was perfect from the start. There were no long conversations. A few pings and a couple of short chat messages were all. Play that felt as natural as a duo who had gamed together for years. Normally, the opponent's nickname wouldn't even be remembered the moment the game ended, but this time was different.

At some point, the first thing done upon launching the game was to stare at the matchmaking window. A relationship where neither knows the other's name, face, or voice. The only things known are a single nickname and the fact that they've been meeting the same user in the same game for seven days.

And yet, for the first time, Kozume Kenma was waiting for someone on the other side of the screen.
