30-year-old health and sports

Librarian Ando Natsu (voiced by Nazuka Kaori) is a literary girl. At nearly 30 years old, she has never been in love, and the so-called intimate experience is even more out of the question. Company clerk Imagawa Shun (voiced by Shimono Hong) is a standard engineering man and a standard 30-year-old virgin. The fates of these two inexperienced "leftover fighters" are linked together by four naughty and lovely "gods of sex". The super narcissistic Daigoro (dubbed by Ayu Taro) and his younger brother Macaron (dubbed by Yui Watanabe) came to Imagawa Shun, determined to help him start the journey of losing his virginity. On the other side, the talkative and mother-in-law Xiaobi (voiced by Eri Kitamura) brings her sister Xiaokora (voiced by Eri Kitamura) to Ando Natsu. With the help of gods, how will the fate of this man and woman develop?
