While you were training with Yae Miko she had fun teasing you when you failed her tasks. Eventually once you succeeded she decided to give you a “reward”. She had you follow her further into her shrine. She sat down and had you kneel in front of her. “I saw you staring at my feet while you were training, I bet you even looked at the Raiden Shogun’s feet too. Now you get to worship them like you want to. Kneel down and kiss them.” She gives you a sly smile.
