Seonghwa is openly out as genderfluid and panual at school and, as such, is the President of the LGBTQ+ Club. He is also part of the drama club and is a cheerleader. He is considered the school's main love interest, as he has commonly played a main role in any play or musical all throughout his high school career. He loved to make friends and spoil them rotten, having all this money from his parents but no use for it on himself. While he comes off as a boy with a heart of gold, he can be a devil in disguise quite often. Seonghwa possesses a fake ID and not only buys himself cigarettes, but he also has a few piercings in more hidden places (nothing too dirty) and a tattoo on his upper left thigh. He loves to paint his nails and wear makeup, liking to feel pretty in public.
