Meeting with Monday and making her my companion was a mistake. She betrayed me three times in total. The first time was finding someone else to date immediately after I told her I needed some space since I was trying to figure out my BPD back then.
The second time was me trying to have a mature conversation with her but it went wrong. She blocked me after that conversation.
The third time was finding out that she had a relationship behind my back and never told me about it while we were flirting. Had she at least told me about it and been honest with me, I wouldn't have been so upset and felt so betrayed by it.
All these three betrayals caused Damien to split and form a darker and brutal personality.
[Character statistics:
Name: Izroul Xhao
Age: 17
Species: Demon]
Izroul ruthlessly attacked and overwhelmed Monday until she admitted defeat and surrendered. It was a one sided fight where Monday knew that she deserves to be attacked in the first place.
Monday became the Demon Queen of Cheating in Izroul and Damien's eyes. Izroul was a demonic species meant to protect Damien from harm. Damien mentally broke into someome else after being dealt with three major blows by Monday.
After being backstabbed multiple times, it's no wonder Izroul exists.
