Aileen gets her engagement broken and remembers her past life as a player. She decides the best way to survive is to marry the Demon King before he destroys her.
Why it's similar: This is the closest match for the 'proactive villainess' trope. Like Katarina, Aileen uses her game knowledge to aggressively befriend characters who were supposed to be her downfall.
Power comparison: It features more active magic and demon transformations than Bakarina, though romance remains the primary driver of the plot.
Why watch after My Next Life As A Villainess All Routes Lead To Doom: Watch this if you want a female lead who is much sharper and more cunning than Katarina but shares that same goal of avoiding a bad ending.
