SONE-577 My overly sensitive female teacher, Rei Kuroshima, is repeatedly summoned to the principal’s office and apologizes for her uncontrollable reactions.

Kuroshima is a slender beauty on the outside, but she has a quiet, timid personality and cannot refuse when asked for help. Because of that weakness, she ends up giving in to the improper requests of a male student and helping him in a compromising way. The one who witnesses this is the principal, a man who embodies vulgarity itself. Summoned to the principal’s office and threatened with dismissal, she is forced into a relationship that is little more than a coercive arrangement. What began as something she hated soon changes her, and Kuroshima becomes a shameless woman, her body reacting uncontrollably. Whenever the principal calls for her, she arrives smiling, flushed with embarrassment, and overwhelmed by her feelings.
