Peatrice

		This is Peatrice, a sweet girl whose occupation of storing items provides little intellectual stimulation. You can store items with her at the bazaar. Due to boredom, she often daydreams of meeting her ideal male counterpart, resulting in a precipitous drop in the quality of her customer service.

Peatrice is in charge of the storage in Skyloft. She lives with her father, the man at Bamboo Island. She's always bored because no one stores items with her. After you visit her for a while, she will start to notice you, and will eventually get excited for all of your visits. This triggers a side quest.

Side Quest

If you go to her house at night (below the Bazaar, next to the small pumpkin patch), you can see a speech bubble above her father. Talk to him and he will tell you that her daughter is distracted too much and that he believes she has a secret admirer, and asks you to break the two of them apart. If you visit her during the day, she asks you to see her at her house at night. For easy travel go to her house and sleep in her bed until night, and talk to her.

Now, this quest can go 2 ways: 1. you tell her you love her or 2. you break her heart. If you tell her that you don't have any feelings for her, she will cry and will treat you like a normal customer for the rest of the game; her father, though, will be happy that she is not in love anymore and give you 5 Gratitude Crystals. I'm not sure what happens if you tell her the alternative since I chose "no", but I believe you still get the Gratitude Crystals, just that they're from Peatrice, not her father.
