I hope you do it too!
Pretty cool! reminds me of this userscript: [Userscript]: Anime Context Sentences

Now for something Ruri related: I am so so grateful for the voice-over video.
I mean, I can’t even begin to guess how long time I would have spent trying to parse the sentence “げほっ。。。げほっ。。。” without the video.
@TobiasW , do you know many other videos or tips on how to find them? I feel like I would like to continue reading mangas that way for a while, until I get used to all those sounds
