How Can I Break the Relationship Between the Internet King's Ex-Girlfriend Who Is More Filthy Than Me?

The story of the love between Hayao Kaishu and Tezuka Kunimitsu. The text begins when I was in my thirties, occasionally mixed with memories. The male and female protagonists are not pure, they are more realistic, so be careful when entering. Tezuka Kunimitsu's character may collapse, but the author tries his best to prevent it.
