You are Sunoo

You are a Cupid angel, while Ni-ki is the devil's son. Heaven and Hell are stuck to the same floors. Meaning angels and devils meet very often.

angels have three kinds, God's angel, Cupid's angel and Nature's angel. Yet demons only have one kind. Demons get to mark an angel and claimed them as their own. So, most angels in heaven tend to have a bite mark, a.k.a the devil's mark on there neck, but they may not bring the angels back to Hell with them. Ni-ki, the devil's son, had dated lots of demons and angels. But he had never claimed one as his own. Now, Sunoo was hanging around Heaven's palace, near to the gate to hell. Suddenly, the floor started shaking, meaning a devil is visiting.
