Congratulations Rein you've successfully messed up the brain of a kid you raise like a beast and his child you bore YOU FUCKING BITCH I HATE TO SO MUCH, YOU RUINED WILLHEM AND HIS SON

rein didn’t “ruin” wilhelm, wilhelm ruined rein. this could been seen in the depictions of wilhelm with the bird, but even more so than that, as the story went on we could see rein’s mental state actively deteriorating because of wilhelm’s gaslighting and manipulation. the whole moral of the story is that wilhelm was ALWAYS this way. he is not trustworthy, he is a manipulator, he is apathetic, and the only thing wilhelm IS consistent at is lying.
even we, as the viewer, have a difficult time discerning what is the truth (from wilhelm) and what isn’t because he literally lies that much. i hate to say it to you, but wilhelm is the problem not because of anyone else but himself.

my brother in christ, she did not have his kid because she loved him, she had his child because she couldn’t bring herself to kill it. and yeah, while did use wilhelm to inact revenge, wilhelm was a willing participant. you make it seem as though she tricked him when that was not the case at all. not only did she make it abundantly clear from the beginning that she would be using him (to both wilhelm and the best friend), she felt overwhelming remorse regarding using wilhelm to advance her goals. of course, that isn’t to say that rein isn’t a bad person as she does some pretty irredeemable things, but i would argue that rein is undeniably human. she never once wielded wilhelm as he was a sword that swung on her word, she treated wilhelm with respect, humility, and civility at every turn in the beginning.
it’s also strange that you frame rein as useless without wilhelm when that is not the case at all. as we can see from the latest chapters, it is not rein that needs wilhelm to continue on, it is wilhelm that requires the constant attention and pampering of rein to operate as normal. it is due to the obsession that rots at his brain that wilhelm is inclined to inadvertently destroy the one thing he cherished the most.
wilhelm is a monster born into a circumstance of his own creation and suffering the consequences that he sowed. the only thing he is a victim of is himself.

Ian is an angel after reading novel if we put ourselves in Ian's foot we'll be able to understand him more like how insecure a person can become bcs of a sudden downfall only if they'd communicated and same goes for 2nd life
Spoiler
Ian was always first to communicate, to help Madelyn but she'd always refuse him and regrets after that and she repeats same cycle over and over and after in 70 CHP Ian finally confessed to her then they become officially couple although alot of things happed in between I've not written here
