I really like that the author didn't drag out the whole saint ordeal and instead passed it off as a one-pager explanation with a somewhat comedic ending.
So far I'm really like where this manga is going. Until... I went to the title page and saw the "harem" tag. This most likely means that the tsundere bitch will come back to MC... It would have been so great if MC just decided to flip her off and stick with the saintess instead, sigh....
