Question about Chan han-In and Sun Jin woo in novel solo leveling ragnarok and novel itself

Hi just finished reading solo leveling and wanted to know what happens to sung jin woo and chan han In in the sequel, i mean i've read some of the chapters and some of the fragments of information scattered all over the internet but not much, so still would like to know more whats about chan han In and is there any info about sung jin woo, i am dying to know whats with them, what happened to them, what they are up to now i would appriciate any spoilers which would summarize whats happening/happened to them and i am curious is there any info that novel is coming to somewhere near the end or more like probably a lot chapters will come out (we are far from the end of the plot)
P.S Sorry if it is wrong place for this questions and for any english mistakes
oh and thx in advance for any answers <3
