Not a glitch. Chapter 19 was added.
Oh yeah you're right, thank you Read was so blinded by the last scene in Chapter 20 that I wasn't looking more keenly to what the changes was. Whispers can't wait for the continuation of the car scene ヾ(❀╹◡╹)ﾉ~
Well the scanlators of chapter 19 are planning to publish their own translation of chapter 20 so if you see Saezuru pop up any time soon, don't get too excited. They've said chapter 21 won't be out till the end of March so heads up.
I don't know if it's the computer glitch or someone double post this Manga after it was updated a few days ago but I nearly had a heart-attack thinking it's updated again. Someone is working to get a hospital bill up in this peace. Geez! Don't do that, head is throbbing over excited.
