Shen Tinghe (attack) × Qin Ge (receive)
Shen Tinghe was originally an experimental subject AIpha, code-named BP-937-x (x). An omaage named "A Qin" filled his entire childhood, and then disappeared from his world. Shen Tinghe also accidentally escaped due to an experiment. But when they met again, they didn't recognize each other. In other words, only Shen Tinghe didn't recognize that this was "A Qin" from his childhood. They only knew that his name was Qin Ge, codenamed Y. They fell in love with each other.
