Wolfwalkers x Male Child Reader

This story takes place after the movie.

Robyn, Bill, Moll, and Mebh have all enjoyed a peaceful life since the lord protector was defeated. They have all actually become a family, Bill Goodfellowe and Moll MacTíre getting into a relationship, making Mebh MacTíre and Robyn Goodfellowe becoming sisters. The two of them were very close as siblings. One night while the two of them were out having fun, they came across a young boy who was all alone. He was scared of them at first since they were in their wolf forms, but eventually warmed up to them. This was the start of some new adventures for the child, Sean.
