YES OK I LOVE BOTH OF THEM ok main difference is that t4t is a time skip while fem is like an au in the story. in the au everyone is genderbend (except for marie i think) but in t4t is just souyuri
some other notes:
-fem!yosuke is named yohi trans!yosuke is named hina, yu is yu always
-yohi uses more makeup and covers up her freckles but hina uses lighter make up, yohi is wayyyy more insecure
-yohi changes her hairstyle every week but the one she feels most comfortable in is a half ponytail
-fem!yu is butch and uses a binder, theres no reason for it shes just like that
-not souyuri but masc!yukiko is mafuyu and masc!chie is senku
-hina and yu have a dog and two cats
-hina and yohi voice hc is tomoyo kurosawa (misaki bandori ily) and yu is mariya ise
-yohi and senku dynamic is like marcille and chilchuck
-yohis first thought when meeting yu was "finally a handsome guy" but when she found out she was a girl she went into a crisis, y'know average yosuke stuff
-t4t souyuri are living the dream domestic life in tokyo sadly fem!souyuri are teenage girls so they have to survive the horrors before getting to that life
