He remembers it little by little (starting from the moment he help the sick Hemoculi by draining their mana at the mining area), but fully remember it is when he become the King of the Hemoculi, which is around chapter 29, can't pin point specifically, but I recommend you read the whole Gray Wall arc anyway (start from chapter 28) because that is peak Eve and Mikael bonding! And if you like smut the rainy day season also a must
Honestly or u can start from chapter 21(5) and it should continue from where the Manhwa left off ahahaha

Seeing the pacing of the Manhwa, 60 chapter more or less? Basically it happens around chapter 29 in the novel, but like yk how they did Korean novel, they have a lot of parts. The Manhwa current at chapter 83 and to sync it with the novel it's actually 71 part in the novel, and from there to where Mikael got all his memories are 50 part away, sooooo yeah

Define "romance" yk how they are, their banter and flirting is still on point but both of them is still pretty much thinking the other doesn't like them that way (or they shouldn't be thinking that way) the Gray Wall arc is really peak OH actually! The Masquerade Ball! Nvm.... that's also 20+ LOL I just counted.... There's still some secret between them but that's def the first tipping point! (Mostly because Mikael gain another memory fragment not long before that) I'm excited just thinking about it ahahahaha
Honestly the novel did a great job of the pace (not dragging each point) my only complain is just Silvestian..... The author keep dragging him around, like let him go! Enough is enough! The poor man, let him move on.... Ugh but anyway I digress.
Omg and the summer festival, I just remembered something cute/funny! It's before The Masquerade Ball! Def within +18 chapter :D

Omg I just realized what u mean... Good god.... The smut is basically in The Masquerade Ball part as well, rainy season is basically them fucking for almost a week ahahahahahaha Idk if the Manhwa gonna show it or not tho, the novel is pretty much a smut on that part
And then after that if they're not working, they're basically bunnies
Mikael after his memories come back is hella cute but there's just something fresh about Mikael before he got his memories back ahahahahaha although I def like the post memories back because it less frustrating.... Anyway! Cute!
