I honestly don't recommend translating this or even reading this if you liked the first one. If you want to know why
author basically says fuck the first part and does a reset writing off the guy from first part (he exists and their relationship is what it is when t+3 first part ended just he doesn't appear as often or much) despite being him being the tsukkomi to her boke for the most part and tries to fill it with other chars
That's a weird move, the romance was definitely the best part of the manga
How long is it? With a premise like that I don't imagine it can be over 15 chapters long or about two tankoubon
