what's the conflict of this story again?

Initially, the mc wanted to avoid her death by breaking up with Leo before her feelings get deeper and follow the novel's direction of her being killed. She is most of the times with Zion because of the broken vial, thus continuing the fake relationship thing. She also wants to prevent Alio from being heart broken so she made Alio keep facing the wall to not meet and fall in love with Yulliana.

got it, thank you

Sure, you're welcome
