Saying Goodbye with Ash and Bones: His Son, He Regretted It

Having a Bitchy Mouth Is a Moment of Pleasure, and the Hero Chases His Wife into the Crematorium!

I want to read a book like "Three Years During the Cold War, He Regreted the Divorce and His Eyes Turned Red". The male protagonist left the female protagonist heartbroken because of his bad words, and then chased his wife to the crematorium.
