What's being posted here is the unofficial translation which was translated using the Korean raws. In lezhin, since they just started releasing I'm guessing they only have one chapter that they officially translated.
Since it's a mature story check the website it should be there
Ok, but I figured it out.
They do not allow mature stories on L3zhin Comics but they also have an app for mature stories called L3zhin Comics Plus
Why can't I read stranger than friend on l e z h I n ?
There's only 1 ch.
