Boram

A high school girl who was a semi-class student like Shin Hye-yul. Before the accident, I get jealous of Shin Hye-yong. After the accident, he joined with two other people and joined Shin Hye Ryul, but he tried to commit suicide by group. It is dead but it is expressed as being reflecting guilt in the mind of Shinhye Ryul. In Season 1, he appeared to be a nightmare or a vain hooligan with a neck hanging or pale shape. In the season 2, he is trying to survive and live like two other people. He said that he heard the news that the ground was contaminated with radioactivity and he committed suicide with Shin Hye-yul, while he was in front of two bodies in the 3rd season.
As for the end of the season 2, there is a lot of the picture that the entrance examination oriented education is centered around the reward in the work. When Shin Hye-yul was ruined due to the rate of Shinhye, or when Shinhye Ryul was suffering from sepsis, he talked to Gyu-cheol about Seoul National University, or Shin Hye-yul stayed at Seoul National University using letters and survived by using Boram. It looks like a coexisting figure.
