What chapter is this in the novel?

This is chapter 24 in the novel but this episode is halfway through the chapter.

if you’re going to read the novel i highly recommend re-reading the entire novel, there’s a lot of details and scenes that were left out of the manwha (although it’s still really well done) :3

What’s the novel called and where could I find it?

It’s the same name, For My Derelict Favorite. and that’s the first link i found on reddit but you can probably find it somewhere else.
