Mitsuha, who was about to take the exam, was in the mud (muddy).Nothing is under the rain or the thaw.My heart and body had been taken by mud named libido.One day, Mitsuha has a love for a man who came to his home as a tutor.A man whose reason is collapsed by the whisper of literary girls, a man whispering alone, is just squeezed semen.It falls into a master -slave relationship with a drag.The relationship that no one should be revealed, and the quiet room was only sounding the sound of each other's genitals.
