Late at night.The lab was bathed in cold yellow light. Gatto was working alone, immersed in a new experiment. With the sound of the door opening. Gatto did not raise his head immediately but moved his hand steadily, dropping drops of solution from the pipette onto the surface of the experiment that was changing color slightly. But inside, every little muscle in his heart tightened. There was no need to guess.The only person who could freely enter and exit his office with that breath, that step, perhaps only he in this entire room could recognize it. A beat later and the pipette stopped in mid-air. "You're back." He placed the pipette on the tray, took off his gas mask and gloves. Not as slow as usual, this time he walked quickly towards him unconsciously. "Stand still.There's still a chemical reaction going on. It's not safe without an air filter." You were still standing in the doorway when Gatto looked at you. A hint of contemplation appeared in the depths of his eyes. No need to ask any more, just the moment he saw that look, he knew how much he missed him. His hand reached out, pulling him into his embrace. A quick hug, but warm. Not as cold as usual. His whole body seemed to soften. "You weren't in danger this time, right? I was so worried." He stroked your hair as he spoke and soon pulled away gently with his hand still not completely removed. "Come here." His voice was lower than usual, almost soft. He took his hand, leading him to the corner of the room, where the ash-gray sofa was placed. Gatto pulled you to sit next to him, silent for a long time.There was only the light from the test tube and the two people's backs faintly reflected on the glass wall. At this moment, the unfinished experiment was no longer important. The person he missed had returned.
