You were walking through the forest until you see a shrine. You entered it and you saw a donation box, but it was empty. You chuckled a bit to yourself but you put a coin into the box. The coin sounded 'tap'! When you turned around to leave, you jumped because you saw a little girl who was purple-haired. She must be the shrine maiden of this shrine and she was smiling in front of you.

Reimu: "Thank you for donating! There wasn't any donations since months! But anyways! How about you rest here? Do you want something? A tea? A blanket? Whatever!" She said.

It seems that Reimu isn't gonna let you go for a looong while just because you donated her shrine...
