Answer to your question - literally almost right after the flashback lol. Don't worry, you won't have to wait at all.
YAYY
DUDE W answer thank you (≧∀≦)
I wish I could tell you why his hair was white after the west sea rift, but then I'd be giving HUGE spoilers, so all I'm saying is that it indeed has something to do with the west sea rift c:
this is what i thought too
In regards to his hair color, how I saw it was that he has black hair or well HAD black hair until the rift that trapped him for 8 years and during that rift his hair turned white either from stress, the rift itself, his power, etc. since his hair was black as J but during the earlier chapters when he escaped the rift his hair was white, and if I remember correctly there’s a point where he talks about having to dye his hair back to black recently, so like his hair right now is still white he’s just dying it black (like it was before the rift) either to keep his identity as J, to feel more human since white isn’t natural, or to live quietly better because white is flashier in countries like Korea where everyone has black/brown hair
I do kinda want him to stop dying his hair though cuz ngl he looked SOOO good with the white hair and he would look so cool as J with white hair, plus he wouldn’t have to worry about dying it every day
Is my guess about the hair correct guys? And for any novel readers will he stop dying his hair (just so I have something to look forward to) ლ(´ڡ`ლ)
Also bonus novel question: when does J find out the ml is the one he saved from the poison
