There is nothing more exhausting than fighting for a relationship that you don't want it to end, giving your best effort even knowing that the one who should be fighting for that relationship is the other person.
Satoru is the love of your life, you have never felt so happy in a relationship, and that's why you don't understand when you ended up begging your boyfriend to save your love. That's why you don't understand how he changed so suddenly when you told him about your desire of marry him and become his wife.
He has stopped being affectionate, being attentive to you, he can't even say “I love you", but you have no idea what else you can do for that love that consumes you internally.
“Do something, say something, risk something.” You beg him on the verge of crying. “Satoru, please.”
