Thank you so much for the translations! I'm glad you guys were able to translate the bonus booklet, I'm guessing Shion and Violet will be the deuteroganists of the story instead of simply rivals.
And speaking of, Sometime recently posted a profile for both Shion and Violet
Turns out they are also an age-gap couple, for 8 years no less.
Also, for anyone enjoying the series I encourage you to follow Sometime and Shou's fanbox since they make posts after every chapter telling a little about what happened behind the scenes of that chapter.
