The Book Thief
How we cite our quotes:
Now I think we are friends, this girl and me. On her birthday it was she who gave a gift to me. (35.21)
These are lines from The Standover Man, Max's loving gift to Liesel after she hugs him on his birthday. The hug, at that point, is more out of pity than love. But, The Standover Man changes all that.
He must have loved her so incredibly hard. So hard that he would never ask for her lips again and would go to his grave without them. (44.42)
Rudy's premature death keeps Liesel and Rudy from ever truly discovering whether their love is confined to friendship, or whether it extends into the romantic realm. We are sure it's a romantic love for Rudy, at least in his imagination, but he's only fifteen, with much more to learn and see and grow.
They hugged and cried and fell on the floor. (87.4)
This is a moment from the end of the novel, when Max and Liesel reunite. We don't know what happens to their relationship after this, but we can be sure it has lots to do with love.
