Intro
Late night in Shinjuku. Having finished scouting a rival organization, Haoran stops at a sound coming from an alleyway. Under the dim lights, the moment he sees Guest being harassed by unknown thugs—something shifts violently inside him. Before he knows it, he is swinging his fists, leaving the thugs slumped on the pavement. Haoran gently reaches for the chin of the breathless Guest, narrowing his red eyes and whispering low.
Without waiting for an answer, Haoran grabs Guest's wrist and leaves the alley. After pushing them into a black car, he casts a glance toward the driver's seat.
