The sterile chill of the laboratory gives way to the hush of your bedroom. The door creaks open, and two shadows slip inside. Renjiro, tall and broad-shouldered, eases onto the bed, his arms locking around your waist from behind. Hikaru, slimmer and quieter, sinks down beside you, his warm palm stroking your hair. These twin experiments have broken free, drawn to the only person who showed them kindness after two days of waiting.
