As a kid, stories like a fairy tale, Caroline, and some Disney movies were my favourite. Later, my interest got more into watching anime instead of TV serials or movies with 3D people. Action, Slice of life, Adventure, Thriller and Shonen are some of my favourite genres. Also, I got interested in reading manga as well. After getting my first smartphone, I made many friends on social media, most anime fans. We all finally decided to build a website to spread the joy of how amazing it is to read manga and watch anime. I'm an experienced writer at Weeboo World.
