Womanizer in another world

This is just an idea that I have that I will be writing on whenever I can..... Synopsis ——————- A 25 year old successful guy that got his heart broken during his high school days. After being so depressed and losing confidence to himself, he found a book that taught him how to live life peacefully. He soon inherit his father’s business and was able to live that peaceful life that he was taught. Until the girl that broke his heart came back, he didn’t care about her and just moved along with his life as that girl’s boss. He was living peacefully, relaxing, having meetings, until his favorite author binirubukuro published another book that is the opposite of what he believed in. Being a big fan of it, he of course read it.......... “Being a womanizer is fine?” He mutters while looking at the context of the book. ————————- I’m not gonna spoil anymore of the prologue. Anyways, this is a story about how a guy became a womanizer (at least the prologue). You can only find out how he died by reading, he is not gonna get killed by a girl (that’s all I’m saying, don’t want to spoil it)
