I Vow Not to Wear Women's Clothes, My Sister Turns Me into a Girl

[Transformation/Sex Change (TS)/Easy Daily Life/Contrast/Brother and Sister] [This story is a fictional creation with an imaginary background, and all technical settings are imaginary] Su Muan is a beautiful boy. After being misgendered for eighteen years, his only insistence is that men should look like men and never wear women's clothing. My sister Su Muya wanted her brother to wear the heavy Lolita design she designed to compete in the competition. After being rejected many times, she came up with a crazy idea: Since she doesn't want to wear it "because he is a man," wouldn't it be good to turn her brother into a woman? Combined with the secret potion of his genius best friend, a quiet transformation began. After seven days, the vocal cords became thinner, and half a month later, the body began to change... When Su Mu'an discovered that something was wrong, there was no turning back.
