Hyunjin and Felix were best friends; Felix and Hyunjin were also transgender men.
The two had known each other since they were little; before the transition, Felix had long blue hair and always wore dresses and delicate clothes.
Hyunjin was the complete opposite; before his transition, he also had long hair, but it was black, and he wore baggy clothes.
It just so happened that when Felix came out as a transgender man to Hyunjin, Hyunjin also confessed that he was, and from then on the two began their transition together.
Today Felix had shoulder-length blond hair and Hyunjin had short black hair; although they still had female reproductive organs, neither of them experienced gender dysphoria and they were satisfied.
Felix was 17 years old and Hyunjin was 18.
