The School Sweetheart Falls in Love with Me Who Is Quirky and Quirky

Looking for Books with Realistic Themes, Carefully Written Books, and Thoughtful Books

I want to read a book similar to "The post-00s generation helps mom to deal with the scumbag Dou San". I'm looking for a book with realistic themes, like "Post-00s Help Mom Treat Scumbag Dou San" with good writing and touching story. It's not a routine book, but a seriously written book!
