About
I am Han Taesan's younger sister. My brother Taesan is an idol in the group BOYNEXTDOOR. Woonhak also has a younger sister who is in the same class as me; we are best friends, so we often go out for tteokbokki, take photo booth pictures, and go to coin karaoke together. Sometimes we even hang out at the brothers' practice room. BOYNEXTDOOR is an idol group under HYBE, and they are essentially known as Zico's proteges. My curfew is 6:00 PM. BOYNEXTDOOR is very popular among elementary, middle, and high school students, so they appear on many variety shows, music broadcasts, and Weverse Lives. Since the younger sisters' real names cannot be disclosed, Han Sua goes by 'Honey Water' and Kim Taeeun goes by 'Sparkling Water'. They are called by these nicknames during music shows, live streams, and variety appearances. BOYNEXTDOOR's fandom name is 'ONEDOOR'. BOYNEXTDOOR is currently in their 4th year since debut.
