Dear Friend

Although she has an estranged relationship with her father, she is doted on by her mother, has a wealthy family, and is beautiful and gorgeous. Lina (played by Keiko Kitagawa) originally had an enviable life experience. However, in Lina's eyes, no one can be trusted, and friendship is just a relationship of use. Arrogant and indifferent, she lingers in the sensual field every night, having noisy and lonely carnivals with others. Lina, who suddenly collapsed in the crowd, woke up in the hospital bed with bad news in her ears. She became ill and had to undergo surgery to remove her left breast. As a girl who was once so proud, Lina's life slipped into the abyss. Even the man who had said endless love words now turned around and left. The appearance of Maki, a classmate from elementary school, brought the lives of these two girls to intersect, and the definition of "friend" in Lina's heart began to change from this moment on.
