There's a support conversation in this game where the protagonist has told a character that they want a gift that money can't buy, so that character hilariously offers them a pebble that they found on the road, and the protagonist is like, "oh ho ho, silly girl, this would only be a good gift if the pebble had some special significance to you." Meanwhile, you spend your time on the Somniel running around picking up items called "Pretty Pebble" that spawn randomly on the ground and giving them to characters as gifts to make them like you more.
