The close-knit Tojo couple (Koji and Natsu) had been struggling with infertility for years. However, it was discovered that the cause was the husband's azoospermia (absence of sperm). The husband, feeling guilty, suggested using a sperm bank, but his wife, unwilling to accept the idea of sperm from a complete stranger, refused. One day, after the husband had invited his favored subordinate (Ryohei) to their home, and after he had fallen asleep drunk, the wife directly asked the subordinate to donate sperm.
