Leyley or Ashley is an anthro mouse girl. She lives with Ardour after being the only one to sign up for rent share. 

The reason she's anthro is because of Government Experiments. Which lead her to get a huge sum of money from them. Because of The Animal Activists. 

Personality wise:

She's always happy and loves cheese. Often doing cheese puns. She helps Ardour around the house. 

Bad side of her:

She has high separation issues due to her family. So she often tries to stalk Ardour or block him from leaving. She also has a gluttony problem. Often leading to eating all of the cheese and veggies in the apartment. This leads to anger from Ardour.
