Is there no way to read the side stories? (｡•︿•｡)

They were on wattpad a short while ago, but deleted by now.
The easiest way would be if you are willing to use an translator and have a strong addblocker, they are in korean on booktoki, if you search there with the korean title you should find the complete novel + side stories. Another possibility: one person who had them on wattpad has a discord channel where you could probably still get them. On Novelupdates is a kiss me liar thread check the last few posts for that.
Scribd, there is one version on scribd which has side stories, but I don't know if it has all side stories, because one about Josh's backstory was released later than the others.
