[HELP] In game narration system

Hi! I'm currently working on **3D** semi open world game in unity. I would like to add In game **narration system** (using a Voice over)/ **Story telling** system like **Ori and the blind forest**. I know about **Fungus** from Unity asset store, but that I don't think will serve my purpose. So is there any other asset package that I can look for or should I use UI text and Audio through code, or there are any other more purposeful way to achieve what I want. Thanks in advance.
