I feel like this manga does a really good job exploring toxic coping mechanisms & the cycle of abuse. It's interesting that every one of the otome capture targets has a backstory that involves mistreatment in some way. The story outright states that the abuse they endured as children is why they ended up as yandere adults - or to equate it to real life relationships, why they become abusive partners.
What really got me, though, is how the heroine is written. It states that she has never had a loving or supportive relationship in her life and above all wants to be loved, accepted and WANTED. This last point is so important when you think about real domestic abuse. Anyone can be the victim of abuse, but individuals who lack a support system or who grew up with conditional affirmations/unstable interpersonal relationships are often targeted by abusers. When I started this manga, I didn't understand why anyone would find a yandere otome enjoyable (outside of ppl who may like that char type), and considered the game heroine to simply be a reflection of the players desires/without any will of her own. But I really appreciate that this manga takes the time to explain WHY she would find the possessive, obsessive personalty of a yandere love interest appealing.
Finally, I appreciate the development of all the main chars. I love me some good character development, and while I think this manga is a bit clumsy at times, I appreciate that it does a good job of balancing how the protag "changed" the other characters with their natural inclination towards toxic behaviors. Wolf, for example, still struggles to resist his impulse to be possessive and monopolistic of the protag. But he makes an active, conscious effort to be a better person.
Overall, I think this manga is a really interesting exploration of the "yandere" archetype and toxic relationships. Is it super duper deep? No, but I think that's part of why it's so enjoyable.
