The story was that a guy got isekai’d but was an absolute brat the first time around. I don’t know what happened but his first time ended. When he somehow came back to the same world, but was determined to hide his identity. The knight who was tasked with helping him the first time though seemed to recognize or at least be suspicious of him.
It was a romance manga that I believe was published online. The guy was an attractive bishounen who would dress in girly Lolita clothes outside of work. His female co-worker was a serious looking woman who would dress in punk clothes to the point she looked more like an alternative guy. They met outside of work, not recognizing each other, and become closer. I think the most recent chapter had them eating at a cafe but had the guy face the dilemma of going to the bathroom and the fl realizing he is actually a guy.
Yelling, “This isn’t some game!” Followed by realizing that it is exactly a game. Always great.
