Using their calculations and blood room is chapter 245
Latest manhwa chapter is chapter 60, which adapted chapters 112-113 in the novel. Assuming that every manhwa chapter adapts 2 novel chapters:
245 - 113 = 132 novel chapters
132 ÷ 2 = 66 manhwa chapters left
Novel chapter 245 may be adapted around:
60 + 66 = manhwa chapter 126
Now every 10 weeks is actually a 1 week hiatus after, so 11 weeks per 10 chapters. For all 66 chapters to be adapted, it'll take 72 weeks aka 16 months (about a year and a half)!
But of course, that's assuming there'll be no season end and they work nonstop So let's assume a year break before they start a new season, so around 2 years and a half possibly

Lmao, to the one who did the math, I love you so much for that, dear. But someone said their first kiss in the novel will be in Chapter 136, which means we only have 11–12 chapters left. Now we have to wait another 2–3 months just to witness their very first kiss.
If you're confused, here's the math:
The latest manhwa update covers up to novel Chapter 113, while their first kiss happens in novel Chapter 136.
So:
136 − 113 = 23 novel chapters left.
Since 1 manhwa chapter usually covers about 2 novel chapters, we divide:
23 ÷ 2 = 11.5
That means we still have around 11–12 manhwa chapters to go.
The manhwa usually updates 4 chapters per month, so:
11.5 ÷ 4 = 2.875
Which means we'll probably have to wait about 2–3 months before we finally get to see their first kiss.
By the way, all credits to hanbina for doing the original math, I only explained it based on their calculations.
