Based on the adult game by Marine.

Kutaro works hard everyday at a TV station as an assistant director. However, his life changes when he agrees to take part in a new TV program with Aya; who is a famous TV presenter, but she constantly mocks him.

One day, Kutaro plots revenge by secretly adding his sperm into Aya's coffee. She drinks it, not knowing, then after work she asked him: "What did you add to my coffee? It had a different taste." He was embarrassed but admits it.

Surprisingly Aya responded with: "Today I felt great. I did not think such a coffee would help...". Thus begins Kutaro's life with a beautiful TV presenter.
