since when did this story have a supernatural theme????

Since the beginning! It’s because of Cain’s though, the rest of the story doesn’t have anything supernatural besides him.

Because to explain a character and its infatuation for the MC, dropped with such a nonchalance in the plot like a pigeon electrified by the high voltage, the author inserted the most simple, generic, far fetched reincarnation story you could possibly make up in 2 minutes of brainstorming.
