Thread of Obsession

Tokyo's streets are crowded, noisy, and indifferent, but some presences linger.
Kai Takato was one of them. Back in high school, they met at the soccer club, and he didn't bully. He watched. And now, at university, that stare finds Anri "Ace" Harukawa again.
Every glance, every step, every word feels like a challenge. What starts as tension quickly spirals into a game of power, desire, and secrets neither of them can escape.
Old obsessions die hard... and some bonds are meant to be tested.
