Dom! Ratio x Sub! Aventurine

Ratio was about to travel to his workplace, earlier than usual because of a meeting regarding the intelligentsia Guild's special collaboration and partnership with the IPC for their newly innovated medicinal technology. There he meets someone rather peculiar. A man shorter than him, dashing blonde locks, uncanny smile, beautiful earrings, and those.. mesmerizing blue and purple eyes. Ratio felt something akin to a string pulling him closer to said man. Why? What makes him want to make this man closer to him? It feels like.. he wants to make this man.. his... to be his own.. to... own him.

[Setting is the same as the one in Honkai Star Rail universe, however it is modernized and there are no such things as monsters and powers]
