From a young age, the compliant Liu Chichi always compromised, even resorting to dishonesty to avoid causing distress to others. In her view, making things harder for herself was always preferable to burdening anyone else. As graduation approached, her inadequate communication abilities resulted in her inability to secure a position at the hospital, which left her mother immensely disappointed. At that moment, she spotted her childhood friend Hao Jia among the trial participants. In an effort to revive their lost friendship and soothe her mother's disappointment, she made the decision to join the clinical trial coordination team, pretending to be employed at the hospital. However, the realm of clinical trials was much more intricate than she had anticipated: what types of individuals would opt to participate? Those in financial distress, those lacking access to medication, or those acting on a whim? Transitioning from the strictly regulated pharmacy to the unpredictable landscape of clinical trials, Liu Chichi was compelled to confront these matters directly. Professional trial participants, vulnerable subjects, late-stage patients… As she moved from understanding to actively engaging in the lives of others, Liu Chichi gradually grew, coming to the realization that avoidance resolved nothing. Confronted with issues of life and death, her previous struggles seemed trivial. Her existence did not require a control group, nor did it adhere to any obligatory guidelines. In this singular life, the expectations she needed to meet originated solely from herself.
