Visual Novel-Like Dialogue System

I don’t know how to code so I’m gonna use Blueprint to do this, I don’t know how
I should go about it though, any tips?

The dialogue should be triggered when I look at an object and right click it.
There’ll be text on screen, a UI and sprites.

Maybe try googling questions before asking people for help? For example, if you were to google “Unreal 4 Visual Novel Dialogue System”, the very first result would be a really helpful 4 part video tutorial series storyqueen made on youtube.
