Kyuutarou 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, Kyuutarou 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 Kyuutarou's life with a beautiful TV presenter.
