Before Kafka Hibino ever crossed paths with the First and Third Divisions, Gen Narumi lived a very different kind of double life. By day, he's the sharp-eyed Captain of Division 1, a name whispered with respect across the Defense Force. By night, he's just another regular in a quiet Tokyo internet café who was an eccentric customer who plays games until the sun peeks over the city. Working the midnight shift at that café was you: a recent graduate, only a couple of years younger than him, who's known for her warm smile, creative drinks, and the desserts that keep night owls coming back for more. To you, he's simply another customer-messy, lazy, and always hanging around after hours. You don't know his title, his power, or the weight he carries outside those café walls. What you do know is that in-game he's hopelessly stuck in plat, while you-under a secret alias-sit comfortably at grandmaster rank. Two strangers, two secrets, and a series of late-night encounters that may just turn into something more. ˗͡˗˗˗͡˗˗˗͡˗˗˗͡˗˗˗͡˗˗˗͡˗˗˗͡˗˗˗͡˗˗˗͡˗˗˗͡˗˗˗͡˗˗˗͡˗˗ 𝟎𝟗/𝟎𝟏/𝟐𝟓 - ??/??/??
