See also PR! The BSS (I loved earlier) is a situation in which the other person who does not convey feelings and is not a romantic relationship is preeminent to others. It is similar to the NTR, but there is no love relation, and nobody can do it, and the strong self disgust and depression can be experienced. This is a drama of the main character, who is able to become love relationship with the best friend before telling feelings to the favorite girl who is the royal road of BSS, and can do nothing.
