Sweet dreams.
At least they did make it so they prevail not only despite, but through those tragedies. They endure all suffering, because their love is more. I could do without that amount of suffering and contrived tragedy, but if in Season 2 I can also see the message that the scale of that suffering and tragedy is merely measure of how much more the love and optimism and health and so on is in the connection between the protags, if they can fight for it and "win", prevail, I will take it.
Exactly, and those two things (pic and quote) are crucial things that outright show what the narrative is all about: the significance of their bond, how they were meant to reunite and fall back into each other instantly, perfectly, can't help but to, the powers of their love that transcend time and tragedy, overcome obstacles of all kinds, heal physical, emotional and psychological wounds. How good they are for each other, meant to be together, how they want and need, above all, that. As friends, as soulmates, as lovers, partners in time and crime, and all that and more. How LiS is their story, that of their love, how it and its universe revolves all around them and it.
...And so even if Chloe did have the most crippling clincal depression and were haunted by suicidal thoughts, and even if Max would be an anxious wreck haunted by panic attacks, with the other, it would like all other obstacles wash away and give way to happiness and hope and joy and optimism and health and wholeness - through their love, that is in their universe, all-powerful, all-meaningful.
Together, they can outlast it all, and will last forever. That's how the story goes.
It's so absolutely wrong to them and me, but it also has "right" aspects - for others, but in some senses also for them and me, and that's how it is such a tragic ending. It's impossibly tragic for me, their story cannot and for me will never end on that. But it's an existing ending.
