Just search up light novel in the App Store (or play store if u have android). For iPhone the icon of the app is blue with an outline of open book. For android the icon is black with the open book. The app is completely free and includes almost all the novels from web novel.

AMAZING!!!! No words can describe this novel!!! Everything was perfect. Best novel have read in my entire life!!! I have one thing to say, you're going to REGRET it if you don't read this!!

This is one of the best novels I have ever read. Although I stumbled on this novel on pure accident, as I read it, I started to love the book more and more.
