Monster Patient. Tayama is a so-called malicious inpatient. He likes the hospital that provides him with everything he needs, and even though his injuries have healed, he refuses to leave. In the end, his purpose in life is to corner and toy with female nurses. The next person Tayama chooses to play with is a new nurse, Aiko. Tayama finds out that Aiko secretly has Kokoro for the hospital director, who is married with children, and uses this as a pretext to corner Aiko... and humiliate her.
