Each arc averages about 20 chapters

Arc 1 - modern day setting. ML is a college student who's pursued by MC (an arts student). During most of the story, ML has graduated and is the CEO while MC is still in college. It's in this story that we get a taste of MC's personality (she was sick and bed bound in her first life btw). Also ML is long term planning cold CEO who's only warm to MC. And the plot derailment - ML has always been in a mutual hate relationship with the plot!OG!FL and has been in love with MC. He played the long game to capture our MC. This first arc is a bit simpler in plot and writing.

Arc 2 - zombie apocalypse setting. The writing gets a bit more complex. There are a greater number of important characters in this arc than in previous arcs. MC is a zombie with human consciousness and ML is her childhood sweetheart.
Arc 3 - modern day setting but in the countryside - MC and ML have an arranged engagement as babies. ML is very poor but has an entrepreneurial goals because MC's scripted character rejects him for lack of money. By this arc, we know for sure that the script from the System is all nonsense.
Arc 4 - ancient setting. MC is a princess. Not all endings are happy 🥲

Arc 5 - modern setting. MC is a child accidentally switched at birth and recognized back. ML is a boyfriend MC made without realizing his identity in the script. The system seems to have given up as we don't get any updates from it; it seems the purpose of the system is to maintain the different worlds but we don't have details.

Arc 6 - republic of China setting. We start with no System intro on the script. It seems the story has already progressed to some degree. Our MC is bridenapped by the ML who is a military leader.
Arc 7 - fairy tale fantasy setting

Arc 8 - martial arts in ancient setting

Arc 9 - ancient setting with spoiled and ill MC. A bit sad this one.

Arc 10 - modern world online gaming situation. Once again our MC is the spoiled little lady of a wealthy family.
Arc 11 - modern day setting and MC is a minor celebrity in a love variety show. MC's background is that her character is supposed to be a money-grubber. I have mixed feelings about this arc. The person I thought would be the ML wasn't.
Arc 12 - modern day showbiz where MC is a secretary who's also a vampire. The System is back in check and now MC has to complete missions with rewards in place (but nothing said about punishments). ML is the president and her mission target.
Arc 13 - I think it's a medieval type setting since there's royalty and related period items? MC is a character that went from rich to poor and wants a wealthy husband. So she ends up with harem of three lmao. I didn't expect that at all. They're even on schedule 😂

Arc 14 - modern day - MC and ML are childhood sweethearts and grow up together

Arc 15 - modern day showbiz - MC is a vase actress

Arc 16 - cultivation world. Some foreshadowing here regarding a possible bigger plot behind the System (there's a glitch at the beginning of the arc). MC and ML are in the same sect but different cultivation groups. ML is reborn and in his second try; he regrets not holding on to MC in his first life so that's his goal here.

Arc 17 - modern setting. MC is a super vain and spoiled character. Each arc MC gets better at adhering to the character.
