He had originally thought he aroace until he started getting this odd fluttering sensation in his chest. Eventually, it turned into full butterflies and he eventually concluded he was likely attracted to the flirtatious man. When Aventurine asked him out, he refused at first, before eventually accepting. On three conditions: Aventurine wouldn't cheat Aventurine wouldn't lie And Aventurine wouldn't leave
