future reader here, i have some questions about the manga!

helloo! after seeing everyone talk about this manga, i'm finally gonna give it a try soon. but first, i had some questions. c:

as someone who doesn't read digitally and prefers getting physical copies, are there bonus chapters that aren't included in the physical copies and that are posted somewhere else by the author? (i'm planning to read the french release or english, whichever is easier to find where i live.)

second, since volume four just released in japan, when can we expect a physical release globally? how did it go when volume three released, how long did it take until it got a physical release elsewhere?

and finally, is it okay to only read the physical releases and not the bonus chapters if they exist? or will i miss out on a lot? (i'm scared of getting lost on how they might fit the timeline if they are not included in the books!)

thank you for answering! ♡ and happy release day to you all.
