Garland is a mid-level adventurer who was tricked by a senior adventurer into taking on a quest that left him badly injured. Luckily, he survives, but his injuries leave him unable to lead a normal life. He needs someone to take care of him until he can return to being an adventurer, but after being deceived by his trusted senior and becoming distrustful of people, Garland buys a former princess knight and her maid of honor who are cursed to absolute obedience to their master. The relationship between the three of them changes during their self-sufficient life with nature deep in the remote mountains.
