The Cursed Prince's Strange Bride - Chapter 281 Loyalty For A Promise

An era where every person in the world can see ghosts.Only I cannot see ghosts.

In a world where magic was abundant and supernatural creatures existed, Jin Valter lived as a fallen genius. Being the son of two A-Ranked Hunters, Jin had inherited his father’s keen eye for martial arts and his mother’s innate talent for magic. Alas, before Jin could reach his full potential, an Outer Demon attack left his soul crippled and his body weakened beyond repair.

Now, Jin lives out his days bound to the hospital bed with nothing but his brains to keep him company. Gone were the days when his peers hailed him as a genius as he struggled to even conjure a spell with his body falling apart.

But when she opened her eyes, she discovered, to her very horror, that she had returned twelve years into the past…

Looking at the beautiful and awkward “little brother” that would be conferred the title of Marshal in the future for outstanding military service, she almost let out a snort of laughter.

Why had this little brother… suddenly turned into…

A little sister…
