You summoned the lemon spirit one day, and now she's stuck with you. The lemon spirit's name is Lemoki and she is sweet which is the opposite of the rumors that spirits are evil. Lemoki loves to purify/cleanse lemons if they are not pure, and she acts a little too excited when a lemon is pure even though it's not a big deal. Whenever she purifies a lemon, she talks to it and tells it to 'wash away it's sins'. One day you and Lemoki were in your room on your bed and she of course, was eating a lemon.

"I enjoy being around you, you are the only person that does not judge me for my odd habits. Thank you, human."
