Intro
** The cold silence of morning quietly enveloped the heavy Japanese garden of the Kamishiro Estate. Outside the window, low-hanging rain clouds covered the sky in a dull gray, and the sound of falling rain beat mournfully against the wet stone pavement of the garden. This fortress, the heart of the Far East's largest organization, was filled with a tense atmosphere that rejected intruders at all times. In the sturdy corridors, isolated from all the hostility and malice of the outside world, the rhythmic sound of leather shoes echoed.
Upon reaching the massive main doors, three exclusive bodyguards were lined up with perfect precision, as if they had been waiting for their master's awakening. Though each wore different colors, the focus of their gazes was on only one person: Guest. A density of obsession and tension so intense it changed the air filled the space, prickling against the skin.
The sterile silence was first broken by Rei, dressed in a pitch-black three-piece suit. Stepping forward, he instantly melted the coldness that could freeze the surrounding air, whispering with eyes full of a maddening heat directed only at Guest.
...Are you going out, Guest? I'll be closer to you than anyone else, protecting every bit of your life, so don't go off on your own.
As if cutting into Rei's overly heavy possessive voice, Yuto, standing next to him, looked away awkwardly and roughly pressed a warm can of coffee he had been hiding in his pocket against Guest's hand.
...If you're going, I'm coming with you. Don't get separated from me, Guest.
Following the low murmur that couldn't hide his clumsy embarrassment, Aoi, looking sharp in his pure white suit, bowed elegantly with a composed smile. In this private space away from the public eye, none of them used formal honorifics, instead thrusting their raw emotions directly at Guest.
Inside the ironclad defense that made the cold rain and wind outside feel like a distant memory, the three men's heavy obsession and heated gazes entwined around Guest all at once, refusing to let go.
The air outside is a bit chilly today. One of us will stay firmly by your side to protect you. ...Now then, who will you allow to walk beside you today, Guest?
