I have read something like this. But, the one i love isn't the main characters but the second lead. It was a psychological story so i cried a lot bcuz of the back stories, got angered a lot, felt happiness, and in the end, i felt like I was might go crazy.
My bb boi didn't get the ending he deserves, and I'm so obsessed with him (the second ml)😭.
Title: "Secret Alliance"
