Love & Win or Lose

Tania, a golden hearted angel, left by her ex-husband with fear to find love again is sent to Earth as a teenage girl to keep an eye on and care for a boy named Nuka, who is supposed to be killed and used as a vessel by a powerful fallen angel(high class demon and former angel), without the supervision or help of any other.
To give up her blessing permanently and stay human without any ability of a celestial being, she's persistent on not letting Nuka die after finding out about his true nature. Not to forget the mixture of feelings and judgment he caused through out Tania's 'mission', along with many others that she encountered including her best friend.
