Vanicia, an elf who is surprisingly "muscle-brained," and Dico, a heavy knight who is a worrier and introverted, are two adventurers living together. Dico, who had collapsed from amnesia, was picked up by the caring Vanicia and started living with her as a dependent――. He finds himself heart-thumping and tossed around by the cute, defenseless, yet caring and reckless Vanicia... While slowly tracing Dico's past without rushing, the two of them are living a peaceful life together.
