Here it is - Chapter 73.2 The Reader and Protagonist Definitely Have to Be in True Love
This chapter is pretty good! The sex scene is quite vanilla and there's nothing super pervy except for the fact that they are pretty much doing it in a public place (the library) where other people could be just around the corner.
I particularly like the sweet, fluffy scene in the beginning where Du Ze comforts Xiu and offers to accompany him wherever he wants to go. If you reread the earlier chapters when Du Ze could barely speak to the Lich, you can really see how much their relationship has slowly grown over 70+ chapters.
We also get a nice view into Xiu's thoughts and why he values our precious little reader so much!
I really hope other people like this chapter, too. I'm still a bit worried about that one review that said the main character and male lead have no chemistry.
