A, after hearing their boyfriend, B, disappeared in another country. Figuring they were dead, A hooked up with Shinsou.
Shinsou, being a tease, always used his mask to copy the voice of their old lover. He didnt mind seeing A call for their old lover during intimate moments, always stopping the moment when A would start crying. Shinsou cared for them.
