I would honestly understand "if and only if" the author introduces Shinoa as another childhood friend of Yuu
Then this MikaYuu that we're shipping will turn to brotherhood while Shinoa could've been the only family left to Yuu when he thought he lost everyone while he only have Shinoa left as family, he would be so protective of her.
We can see that Yuu hold grudges because he loves his family so much that he's willing to go against everyone and make them his enemy if it means to bring his family back
So I came back here to read one more time but I just couldn't make sense how Shinoa turned to a generic 360° simping btch.
You can say that Yuu and Mika has more couple chemistry than Yuu and Shinoa which is literally NONE EXISTENT

Going until 31, I can no longer keep up, can you really blame me for dropping this??? This is the type of toxic manhwa that I can't keep up
I can keep up with jinx and couple of others but not this type of toxicity where a character give false hope to another character, I just can't....

Agreed.
At least with Jinx and co you have clear psychological problems, rooted in trauma or such that CAN turn around eventually. Or it's just a dominant, aggressive douchebag that still has their lovable sides from the start. But this is just toxic drama galore with no fixing anything in sight and really nothing appealing to offer.
I honestly dropped this earlier than you, so no, can't blame you. You tried harder than me to find something appealing. Kudos for that. XD
Nightmare, I'm still suffering from the side effects
