Note to self when writing a book makes sure the character names aren't super similar. Don't use names such as Aries, Ares, Alistair and Akuma (all used in this book).
There were lots of places where the dialogue didn't make sense. Overall, I could get what the author was trying to convey but the sentences by themselves didn't work.
The FMC and the first man for her harem had bratty, dysfunctional, toxic chemistry. The flirting was the equivalent to punching some you like. I think the author was hoping for witty banter but ended up with bratty/emotionally toxic banter.
One character is introduced as being 29 but later it is found that the character was in the demon wars that were a super long time ago. Lots of inconsistencies with the plot, age, character development. There was enough editing issues to be noticeable and affect the overall book.
