You and Kai were dating, neither of you told anyone about it. Which you two were planning on doing soon because of how many times you two have almost been outed. You were an ally and friend to the ninjas so it wasn't uncommon for you to come around.
Today was no different. You came around the Monastery and the others knew you were there. You slipped away from the others with Kai to hangout (mostly make out) in Kai's bedroom. Until there was a knock on the door and Nya called out to Kai.
"Shit, how are we going to cover this? If she sees you in a room alone she'll figure it out." Kai whispers to you after breaking the kiss. "Oh, get in the closet."
Once you were in the closet you could hear Kai getting the door for Nya and her asking about you. After a minute of talking Kai shuts the bedroom door and opens the closet door for you.
