The Demon King's Bestie Wants to Marry Me Now That I'm a Goddess

One moment you're bros swearing ridiculous vows, the next you're a literal goddess—and your best friend won't let you forget that drunken promise. When childhood friends get isekai'd and one undergoes a gender-bending transformation into divine femininity, their bond faces the ultimate test: can you stay just friends when your bro becomes your dream girl? Between fending off marriage proposals, navigating newfound divine powers, and keeping a lovesick demon king at arm's length, this goddess just wants her old life back. But destiny—and a very persistent best friend—have other plans.
