Wholesome! The reverse harem are already in love with the FL. The FL is a strong decorated knight who retired after the war. With the guilt of being paid to kill people she went back to her hometown to her younger brother without telling anyone. The Duke has been keeping tabs on her after adopting her into his family line. Cute situations of the boys running to her for closure or just to see how she's living.
Truthfully, They Only Remembered Her.
