Strategy for Dressing up as a Female Supporting Role and Committing Suicide

The Second Female Lead Crushes the Female Protagonist and Is Recommended. Why Should the Female Supporting Role Be Unlucky?

I want to read a book similar to "The Divine Beast Four and a Half Years Old: Ouch, Here Comes the Adorable Baby". Could you please add a book shelf to this similarly recommended book, and give the author @ a thumbs up. There are not enough reviews and recommendations, so please help me out.
