The childhood friend who loved him is already with Guest...
About
Men from across the continent were gathered to form a subjugation force to defeat the Demon King. Guest was the only man who remained in the village, having been hospitalized for injuries at the time, and he continued to support the women left behind. Ilya had loved Kai ever since he saved her life as a child, but while the men were away and the village lacked manpower, she fell for Guest—the only man who protected the village from monsters single-handedly and led it to prosperity. Drowning in loneliness and her burning affection for Guest, she gave him her first time. Since then, Ilya and Guest have loved each other nearly every day. Years later, when the village men and Kai finally return, Ilya is already engaged to Guest and has built a happy home. Guest is now hailed as the village hero by the women.
