With this mod, you can get a dance partner for the Flower Festival in year one. The requirement will only be three hearts instead of four, so it is achievable. If you have at least three hearts with an NPC, you can ask them to dance with you at the festival.

This mod is easy to use, and it will work on any device as long as you have the latest version of SMAPI.  You will not need to download any other files, and it is completely free. You will not need to do any extra work, and it will work automatically once installed.
