 Some denizens of Chulip only come out of their underground , living apartments through holes in the ground at certain times of the day . If the player looks through these holes , clues are given in regard to when they come out or when to kiss them . After an NPC comes out of the ground , the player has a very limited opportunity to give them a kiss . If the player successfully kisses enough NPCs and returns home to sleep , the hero 's father will recite his progress and the Lover 's Tree will give the player more hearts and an improved reputation if he advances . Secondary to improving his reputation , the player must track down all the pieces to the " Love Letter Set " by traveling throughout Long Life Town . As the story progresses , the player gains access to new areas of the game world via train , which include many more underground residents and hazards . Saving takes place in various bathrooms .
