Review Detail of Imago_Dei in Trial Marriage Husband: My Bed's Broken!

I added this because I liked the preview and the first 20 chapters were really good. However, the plot seems to be off-track and rushed. Characters were coming in, FL suddenly has a twin, she suddenly knows martial arts, there were suddenly mafia-terrorist fights and the ML's backstory is so inconsistent. I feel like the author has potential but he/she seems to not have a solid plan as to how she wants the story to be.
