Pretty standard fluff for this type of story but it was well-written and the translation was superb so it was hard to put down. I liked that the ML knew pretty quickly that MC wasn't the same person though I really couldn't figure out why no one else in his life questioned it because he seemed to be a pretty radically different from the original goods. Still, it was cute. Nothing surprising or original really happened in the story but it was still entertaining.
I think the only question I have about this story was what business, exactly, he was forced to do? Unless becoming bros with the protagonist of the story counts as business????
