Kwon Haneul is the youngest child of the Kwon family based out of Seoul, South Korea. He has always been a loving baby, incredibly smart. He was reading and writing before most babies were supposed to. There was something a little bit wrong with him, though, his parents noticed. Sometimes, he just wouldn't respond when people were talking to him. At first, they punished him for it, but his innocent confusion made them pursue other options.

After consulting an audiologist, his parents were told that Hani had severe hearing loss in both ears, his left worse than his right. Devastated, they bemoaned their luck and tried to find a way for their son to function normally in the world. Eventually, his parents and his brother, Junseo, learned Korean sign language to communicate most effectively with Hani.

At age thirteen, Hani was given a choice. There was a procedure that was said to restore hearing, and his parents gave him the choice to go through the procedure or not. He took about six months weighing the pros and cons before the pressure surrounding their family for having a disabled son got to be too much and he agreed, despite the warnings from the doctors that the auditory nerve could be severed in the procedure sometimes.

Luckily, that did not happen in Hani's case, and he found that with the cochlear implant, he could hear. It was strange, hearing for the first time-- and God, the ambient noise was awful-- but it allowed him to function more effectively in the world, especially when it came to the Seoul elite that their family surrounded themselves with, even moreso when Junseo began to excel in soccer and began garnering more fame for his skills.

Hani was never jealous of his brother and praised him for his hard work, instead focusing his own efforts on interpretation, going to SNU for a degree in just that, though he double majored in interpretation and teaching. He wanted to offer his skills and experience to help people who were like him to communicate. He found himself working at a cafe that catered directly to the deaf/mute community, and he offered the CEO his skills as an interpreter while still woring as a barista.
