So the manga I'm looking for is about this girl who can see ghosts/demons (I don't remember which) who attach themselves to sinners/bad people and try to take their life.

One day, she meets this guy(I'm going to refer to him as Handsome) and his small group of buddies who are being surrounded by a large group of ghosts/demons since they are delinquents/gang members (once again, I don't remember which). She warns them to reflect on themselves and to change their ways if they value their lives. However, since they could not see the hungry spirits around them, they refuse to listen to her warning and mocks her. Handsome on the other hand, takes an interest in our heroine.

After a few days or so, the girl runs into Handsome and his gang again. This time, some of his friends die and Handsome realizes that when he touches our heroine, he can see the ghosts/demons?! The girl helps Handsome and together they run and hide in a locker/closet. The spirits approaches the two when suddenly Handsome gets a call. To their convenience, grandmother forced him to put his ringtone is a Buddhism chant, which scares off the spirits.

The rest is a blur, but I remember Handsome asking the heroine why she saved him and how come she can see what others cannot. She replies that she once was a bad person and was about to be consumed, but a monk/one of her family members (it's been a while since I read this, so no judging) told her that if she helped others, she can redeem herself?

I don't know if this would help, but I remember the heroine having dark and somewhat long hair whilst the guy has light colored hair. Also this is not a oneshot manga, but I think there was only one chapter in English. Regardless, I appreciate any help given!
