Everyone is shocked at Skylar's cruelty me included. But what he said isn't so different than what many people say: you can't love others until you love yourself. Which isn't true.
Having trauma doesn't make you unable to love in most cases, it's just a constant interference.
This is so realistic, both are very immature with zero self awareness. They're cruel because they're hurting so much.
But isn't the rating a but too high for this? The storytelling is mid and rushed. And we've all read this kinda story before... It's not bad but for all these reasons it's not very engaging :
