This is one of those manga i needed to finish. I can only say that being alone is painful and that having someone you love close to you might be the best thing there is.
I loved their journey very much... this end tho. Felt so unfulfilling. Not enough food or water to even reach the level bellow. They risked everything in this last sprint and lost. The only logical outcome now is the saddest i would've expect.
That surely made me depressed.
