(Short Story Version) The Femboy Wants to TS! To Marry His Male Best Friend, He Searches for a TS Method in the Dungeon!

On the day of their high school graduation ceremony, a man and his childhood friend's daughter become a couple. They decided to attend the same university, and the two thought they would be able to spend happy days together from now on. However, the anxiety from the wall of gender differences and the sadness about "things they cannot do" do not disappear so easily. But fortunately or unfortunately, dungeons appeared in the world ten years ago. If that's the case, then it wouldn't be strange for fantasy like TS (transgender transformation) to exist! They will absolutely find it! This is that kind of story.
