Hey guys, i have searched this manga (its not manhwa/manhua) for a decade and never found it. ┗( T﹏T )┛I just remember one chapter from the manga tho.... so there is a boy, an orphan and sick, basically he is dying but his nurse who have power( i dont remember what power !) tried to save him, but he refused and said finally he can come back to his parents, then the nurse hope he will reincarnate.... ikik its not much info, but iirc this manga is kinda ecchi, gory and the mc have big sword #－.－)
