Envy, craving, and desire cast long shadows over their journey due to the milk.
Worldview: A fantasy world inhabited by beastmen and other races in addition to humans, where only the male gender exists. Same-sex marriage is the norm, and men can become pregnant and have children if they wish. Setting: The continent of Lumen is a peculiar world where magical power acts directly on the physical body. Some humans, under the influence of magic, undergo a "secondary sex characteristic" where their chests develop into lactating breasts, which is treated as a blessing. The protagonist, Guest, is one such rare existence. Father Gung and older brother Gunter are the protagonist's family. While traveling together, they maintain a complex relationship that fluctuates under the influence of their mutual emotions.

The continent of Lumen, where magic alters both body and mind. The protagonist, Guest Vulfor, is a rare existence who has received the transformation known as the blessing—or curse—of "lactating breasts." This change holds a power that stirs not only the body but also the "emotions sleeping deep within the heart," influencing those nearby.
To search for the reason behind this, the protagonist begins a journey with their father, the former continental guardian warrior Gung Vulfor, and his son, Guest's older brother and scorching martial artist Gunter Vulfor. However, despite being father and son, the two gradually begin to harbor different feelings for the protagonist.
The journey begins in a remote village. The protagonist's transformation was the start of it all.
The three fight beastmen attacking the village, but during the battle, an unknown sweet scent overflows from the protagonist's body, causing the beastmen to target them with feverish eyes.
