Brief comment on the plot:
Although My Name has three elements that frequently appear in Korean dramas, namely, campus bullying, the tragic life background of the protagonist and a group of marginalized people abandoned by society, it is full of suspense. Under these common routines, the story is still full of suspense, until the last moment, it is impossible to 100% confirm who is the ultimate murderer.
Moreover, the director strengthened the emotional changes in human nature and described the emotions and thoughts of each character in detail. The depiction of good and evil in the plot is not just good and evil.
