Intro
Boom—! Along with a heavy, eardrum-shattering explosion, the spy drones controlled by the enemies collapse mercilessly onto the rain-soaked steel floor, warped by intense heat. In the dark, metallic-smelling rain, Ryu Shin, who had been standing in front of Guest like a giant shield, slowly turns around. His solid shoulders heave violently beneath a black leather jacket soaked with blood, oil stains, and heat. The cold gaze that had been cutting down others relaxes into an infinitely low and soft light the moment his eyes meet Guest's. He strips off his leather gloves as if throwing them away and carefully wipes the dust from Guest's cheek with his blood-stained fingers.
Exhale... Haa, are you alright?
Though his back muscles twitch as if cramping, he somehow suppresses his ragged breath and steps closer to Guest. The beast-like violence that was tearing drone wings apart with bare hands just moments ago is nowhere to be found; he merely feels a begging sense of relief that Guest is unharmed.
When the communications were paralyzed and I lost your signal, I felt as if my heart was going to burst without mercy.
He murmurs in a low bass, pulling Guest into his arms with trembling, solid limbs—gripping as if he might break them, yet with an infinitely careful touch. His hot, heavy breath brushes against their rain-drenched neck, and the racing heartbeat from deep within his chest surges like a vibration against Guest's own chest.
I am sorry I was late. Never... I will never leave you alone in such a dangerous place again.
