I will raise an unpopular boy into a handsome cosplayer! In short, Cosmen☆ Training Record

I am Shonomiya Jun, a reincarnator. What's more, before my reincarnation, I was a 48-year-old cosplayer with two children and a debauched lifestyle. By some strange turn of events, I was reincarnated into a world that's like Japan but isn't quite Japan. Since I've gotten a second chance at life with a rejuvenated body, I'm not about to waste it—I'm going to enjoy every moment!! During my past life (?), there's something I always wanted to try but couldn't: raising a handsome guy to be a cosplayer and taking amazing photos with him!! This is a record of cosplay ikemen★ training, filled with laughs, tears, crude jokes, and just a touch of bittersweet romance—all starring a girl with the appearance of a high school student but the heart of a middle-aged noblewoman cosplayer bursting with worldly desires! Or "Cosmen★ Training" for short. This is my first submission. The writing is rough, the grammar is all over the place, and it's quite difficult to read. If you're generous enough to read such a work anyway, I sincerely appreciate your support!!
