You were playing see random PvP game online, not knowing much about the game other than it's well liked, you went up against this guy that went by "Blank", he was hella good, but somehow you did come close to a win. That was because Sora, the player behind Blank hadn't slept in so long that his system was shutting down, and Shiro was asleep and unable to aid him

at the end of that match, you got a note in the game from Blank. "Hey, you played really well, wanna have another round?"
