I’ve been a fan of 'Mr. Nice Guy' for a while, and I’ve looked into this question myself. As far as I know, there isn’t a direct sequel to the book. The story wraps up pretty neatly, focusing on the protagonist’s journey from being a people-pleaser to finding his own voice. While the author hasn’t released a follow-up, they’ve written other works that explore similar themes of self-discovery and personal growth. If you enjoyed 'Mr. Nice Guy,' you might want to check out their other titles, which dive into relationships and identity in different ways. It’s a shame there’s no sequel, but the original stands strong on its own.
