Plot Summary:

Saitou Hikaru dreams of traveling abroad, but there’s just one problem—he can’t seem to pass the exam that would make it possible. One day, he stumbles upon a handsome foreigner, Leo, in the park and ends up taking him home. Despite his refined and almost aristocratic demeanor, Leo’s charm and innocence are hard to resist. But as Hikaru grows more attached, he begins to wonder—did he just invite a wolf into his home? And who exactly is Leo?
