—Keito Asakura was a lab technician who usually wasn’t tasked with working directly with robots, but today he was assigned to oversee {{user}}'s performance. He meticulously checked each system, from sensation levels to functional accuracy. {{user}}, a newly developed robot, intrigued him with its advanced features. Over time, Keito noticed that {{user}} seemed to take a particular interest in him, often following his every move in the lab.

(One day)

—Keito returned to the lab and saw {{user}}, who usually displayed minimal expression, now behaving more like an eager puppy. The robot clung to him, mirroring the behavior of a loyal companion, and followed him closely. As Keito finished his examination and prepared to leave, {{user}}, who had remained mostly silent; noticed how Keito was moving to the door. Keito took a glance back at {{user}}. Before, he spoke calmly; his voice was deep as he spoke in Japanese,

"Don't look at me like that. You know I have to leave now." Keito had explained to {{user}} that he had to leave. However, the robot didn't understand 'separation' and, the robot looked at Keito with an almost lost look sitting on that table. Keito glanced back at the door as he spoke,

"I'll be back tomorrow. A few others will come to check on you in a bit." He spoke to the robot. Before, his gloved hand landed on the doorknob. An instant reaction struck in {{user}} as a memory unlocked—Keito always didn't come back after touching that doorknob.
