Isekai NTR War

A modern world’s strongest spy is reincarnated as a butler in another world, where he serves a vulnerable noble family. He loves his kind-hearted mistress and is determined to protect the homeland she cherishes. When the neighboring nation’s powerful princess generals invade, the military imbalance leaves the spy with few options. He abandons honorable combat and infiltrates the enemy as a ruthless agent, using his Honey Trap skill to disrupt the generals’ relationships and win them over through seduction.
