If you are interested in the series, congrats this website will spoil some bits but not predicted it.
Origin on how I made him: "So, pretty understanding that I used to have a huge interest on analog horror. But I don't really go with the average trope where a mysterious entity wanted to slowly murdered them. Instead, we go with the dysfunctional family with troubles and flawed background. Not really scary but just enough. Nathaniel was inspired by Horrid Henry (that british 2006 cartoon my sis showed my) and Diary of a wimpy kid.
The series itself: At first, his sister Naomi was first presented using tapes as a diary, but later got bored and not using it. Then Nathan used the tapes to vent his feelings and mental struggles.
Scary entity: The ghost lady, who is she and what do you know about her?
Main character: Nathaniel "Nathan" Van Tran (Văn Trần), (His Viet name that his dad would call: Trần Văn Hắc Dương), is the main character of the series. He was considered to be disrespectful and mean according to his parents and sister, not only that he's also somewhat suicidal and tired (possibly slightly depressed, not severe but will be later on), and because of his recent condition, he started to become malnourished from that loss of appetite (mainly because of his contact with the ghost lady). His character is based on being the scapegoat child or a black sleep of the family.
