Yuri just proves that men & women, het & homo are the same - they just want successful younger model/actress/rich person to unconditionally love them for who they are.
Fan-insert MC-shipper characters nearly always make the story worse, hate this trend. Same with the butler in the wolf-manga, or the alien bird, or the alien yuri shipper from the other recent mangas..
damn, I must say you are picking some of the best series on this website for translation, 90% bangers (and even those that are not bangers start as such)
