This sequel would probably make a whole lot more sense if UGH - Kiss and Kill with Norman, Erie and Mutou had been fully translated. I'm trying super hard to follow the damn story based on what I remember from Kiss and Kill. Lets all pray to the Translation Gods to complete Volume 2 of Under Grand Hotel: Kiss and Kill. ┑( ̄Д  ̄)┍

It's actually complete according to my research, the released mangas are:
1. Under Grand Hotel (main story)
2. Kiss & Tell (spin-off Vol.1)
3. Last Dinner (spin-off Vol.2) - this is the vol 2 you're looking for, the one that goes right after Kiss & Tell storyline. You'll see that the beginning of this & the end of Kiss & Tell match perfectly
4. UGH Crossover (current one)

Last Dinner starts at Vol 2 Ch 1

Please don't thumbs down...I have a philosophical question. IS he ...ing the dog??? I mean it technically is his boyfriend...or is he letting the dog sleep with other dogs? Did he spay or neuter his dog/boyfriend? I HAVE SO MANY QUESTIONS.

Yall can chill. He's probably keeping him as a pet. Lik those annoying pet owners that love their dogs more than their kids. This is that that fucker devil's fault for saying things lik kinky and shit. Nicholas clearly waited before and he gon wait after as well. Lik fr sensei really should've spared us of the second story it really ruined the feeling of the first.
Oh sweet Rin-sama! You have saved us all! Thank you!
