Kim, Seokjin

Named after and based from BTS' Jin, Kim Seokjin is the protagonist and narrator of Save Me, and is the prime mover of the story's plot. He became friends with Namjoon, Jungkook, Yoongi, Hoseok, Jimin and Taehyung when all seven of them received detention for being late to school and is the oldest among the group. After their group's separation, he stays in the United States and returns home two years later, only to find his friends plunged into their own miseries. In his wish to reunite with his six best friends, he gets trapped in a time loop, from which he could escape only if he could save all six of his friends from their ill fates. He repeatedly relives his life starting April 11, learning the rules of the time loop in each iteration to bring all of his seven together.

[Spoiler] In the last episode, he is killed in a struggle with Taehyung, who has turned murderous against his own father due to violence in the family. [/Spoiler]
