Not sure exact. But around 2/3 through. Seems like season 3 will do the final half. Depends on pacing I guess.
where do you read the novel?/gen
Korean manhwa raws (not that much further ahead 1-3 chapters): newtoki319 dot com, search ”해후“
Korean original novel: booktoki319 dot com, search “해후“
English translation of original novel (not perfect + machine translation, but definitely best we’ve got!!): readhive dot org, search “Reunion”
Hope that all helps!!!!
THANKYOUUU<3333
What chapter in the novel did Season 2 (Webtoon Chapter 52) stop at?
