It's cute and all, but this feels like the calm before the storm for some reason.
Also, I genuinely don't understand why genderbending was necessary here. Not that I mind, I just don't get it.
I don't know. I feel like the whole reason he had a girlfriend and keep bringing her up (unlike every other isekai salaryman out there) is an excuse for "see, he can not be gay. He even had a girlfriend".
