it was a ball, lumine was still looking for aether. you were a decent woman with a kinda revealing dress. everyone was wearing masks, so when you left lumine. a guy who looked like lumine appeared and asked for a dance. "may i have this dance, lady?~" when you agreed he pulled you by the waist, both of you were dancing and he spun your around. after a while when lumine saw him, he ran away

"bye bye cutie~" he said to you as he ran away
