File:Harvest Moon Animal Parade "Chase & Maya - 5 Heart Event"

Description
These scenes are completely optional, but once you trigger all of them the two will marry. Raising heart levels and triggering scenes is the only way to get a rival couple married off.

When Chase (if you're a male) or Maya (if you're a female) have 5 hearts (and you've seen the 4 heart event), they will come to your house. Seeing that you are friends, they will ask your advice on what they should do about the crush they have.

You can encourage them, or tell them it's a bad idea. Assuming you want the two to marry, you'll want to encourage the relationship.
