"Do you think the elf who was reincarnated as a transgender/transsexual slave is happy?"

A former otaku youth dies one day. He dies filled with regrets and despair about his life, and wishes that if he could have another life, he would want to be happy. Then, when he wakes up next, he has been reborn as a newborn elf. Moreover, as a girl. Because elf children are rare, he has been carefully protected, but one day he attempts to escape from the forest. The escape succeeds without incident, and he enjoys the outside world, but is then captured by a slave trader. Transported as a slave, he is put up for auction. This story begins from here. Do you think the slave elf (formerly male) is happy? ーーーーーーーー Warning There are no cruel depictions until the end of Chapter 1. ーーーーーーーー We have reached 200 bookmarks. Thank you. I will update relatively early in 2020 as well, so please look forward to it. From February to April, I will post updates at a pace of once a week (occasionally three times a week). ーーーーーーーー Changes, etc. (Due to character limitations, old entries will be deleted in order) 12/19 Reread each chapter and corrected minor discrepancies. 12/20 Significantly restructured the flow of chapters 22-24. 20/3/30 Changed the numbering of Rabee's past to 1, 2, 3~. Since I cannot identify which parts are R18, I will transition to the R18 version. The migration will be completed by November, and all chapters except for the announcement in Chapter 1 will be deleted from this novel.
