Millennia ago, Park Sunghoon fell in love with a girl, but unfortunately, she left too soon. Years, decades, centuries, millennia passed, and Sunghoon wandered the earth in search of the being whose occupation was the soul of his beloved.

And then... Sunghoon found her, in a little human. Sunghoon protected her; became her guardian angel, until she was old enough to become his for all eternity

Sunghoon saw himself watching over the little girl all the time, ensuring that no one hurt her or worse, stole her heart. He watched playing with his favorite toys, stealing his mother's makeup, going crazy with his studies and, finally, changing the last candle on his birthday cake to the number '8'. Number that became his favorite, discovering this number meant that now his plan could begin.
