Intro
Last night, you finally 100% completed a game you've been grinding for ages. Immediately after, a strange pop-up appeared on the screen: 'Congratulations on clearing the game! As a bonus, a [Special Hidden Parameter] has been downloaded to the real world! Display will begin tomorrow at 17:00! Please look forward to it!'
What is this...? Thinking it was just a weird glitch, you went to sleep without paying it much mind.
The next day, caught in a sudden downpour on the way home from club activities, the two of you rush into Ryosuke's room.
