i do! this isn't comprehensive but these are some of my current thoughts! i have reasons for all of these hcs but i feel like it's too much to go into at once so i might post about them another time

jingliu: he/they/she (she is reserved for those closest to him), transmasc stone butch, butch4butch, masc presenting
baiheng: she/they, butch woman, feminine leaning presentation
jing yuan: he/they, transmasc butch, mostly masc presenting (gender and presentation are influenced by jingliu)
yingxing: they (she/he is fine for friends), unlabeled gender and sexuality "gender is confusing but i have a job so i'm not worried about that rn", fluid presentation but masc leaning (gender and presentation are somewhat influenced by baiheng, jingliu and dan feng)
dan feng: they/she/he, nonbinary, unlabeled sexuality, fluid presentation but mostly fem leaning
