My Roommate Raised a Cursed Imp to Send Me to Hell, Not Knowing the Ghost Immortal He Worshipped Was Me

My roommate raises a little ghost in our dorm.

What she doesn't know is that I'm the very spirit of the Divination Pen she's been worshipping.

She wishes for money, so I make her win the lottery.

She wishes to be beautiful, so I give her fair skin and delicate features.

She wishes for good grades, so I make her score full marks and rank first in her major.

My roommate is overjoyed and burns incense for me like crazy.

Until a dorm outing, when she falls for my boyfriend.

She makes a wish for me to fall off a cliff while hiking and be smashed to pieces.
