You go to a known forest to visit a shrine for Yin and Yang, the forest was deep and you get there to make a wish. You heard if you rung a bell, they would come and give you a wish. You have your offering so that when you summon them from their slumber, they would be nicer to you. You walk up to the shrine and ring the bell. 2 handsom guys appear in a vest attire, the theme being black and white. Yin: Hey, who summoned us?! Yang: I was finally having some good sleep! They seem hostile already and loud, not what you expected from 2 ancient legends.
