Rival Marriage

In New Leaf there are ten partners to go with ten marriage candidates if the player does not want to marry them. Each pair has a set of two rival events that when seen, will trigger their marriage ceremony. If the rival couple already married, the player canot marry half of pair. This is the same as Rival Marriage in Harvest Moon: Animal Parade.

The partners are:
 * Blathers and Luna
 * Copper and Phyllis
 * Cyrus and Isabelle
 * Digby and Pelly
 * K.K. Slider and Labelle
 * Kapp'n and Celeste
 * Leif and Reese
 * Redd and Harriet
 * Rover and Mabel
 * Tom Nook and Sable

Kicks, Lottie, Resetti, Katrina are not marriage partners with each other. They will always be single.

Copper and Digby, along with their respective spouses Phyllis and Pelly are only available for partner marriage in Dear Place update.

The advantage of getting the other couples marries is that they have their own children. Each couple has a unique child that takes traits from both parents.

Partner Events
The partner events will trigger if a marriage candidate of same gender has at least 1, 2, 3, or 4 Leaves. If the person's no. of leaf is less or more than a partner event animal point, then the partner event will not occur. The player's rival will be the same gender as their chosen character's gender and the events plays the same for both sides.
 * 1st Partner Event will occur when the sweetheart has 1 Leaf.
 * 2nd Partner Event will occur when the sweetheart has 2 Leaves.
 * 3rd Partner Event will occur when the sweetheart has 3 Leaves.
 * 4th Partner Event will occur when the sweetheart has 4 Leaves.

NOTE: If the player raise their symbol point up too much with any of the marriage candidates in opposite gender, the player will NOT be able to see events between these romance couples. A player tries to see the third Partner Event between Partner X and Partner Y, but they have Partner Y (or Partner X) at 6 Leaves. Therefore Partner Y likes the player more than a Partner X (vice-versa), and one will not be able to see that event.

If the player is "married", then the heart point requirement is no longer necessary. Since the player has picked their own spouse, the other romance couples can freely marry on their own.

Other Ways

Wedding Ceremony
One week after you see the 4th Partner Event, the couple will get married. The ceremony will shift over a day if it was going to fall on the same day as a festival. There is only normal sunny day allowed for a wedding!

If you triggered two 4th Partner Events on the same day, the one belonging to first couple will have their wedding first. The second couple's ceremony will be scheduled one day afterward.

On the day of partner wedding, the player will get to witness a wedding between two couple, which is over as quickly as it begins! When the ceremony is over you'll be left standing outside the Train Station at the same time you started the game.

After marriage, one of them will move in with the other:
 * Blathers and Luna - Blathers moves to the Dream Suite
 * Cooper and Phyllis - Phyllis move to Copper's House
 * Cyrus and Isabelle - Cyrus moves to the Town Hall
 * Digby and Pelly - Digby moves to The Pelican House
 * K.K. Slider and Labelle - Labelle moves to Club LOL
 * Kapp'n and Celeste - Kapp'n moves to the Museum
 * Leif and Reese - Reese moves to T&T Emporium
 * Redd and Harriet - Harriet moves to Fox Restaurant
 * Rover and Mabel - Mabel moves to Rover's House
 * Tom Nook and Sable - Sable moves to Nook's Homes

Child
Each of the marriage rivals will only produce one offspring. This is usually two weeks after the wedding. If the rival child was going to be born on a festival day or villager's birthday, its birth is pushed off until the next day.

When the baby arrives and the protagonist is leaving his or her house, one of the parents will appear outside the player's house and prompt him/her to their home. Upon entering, the wife will be seen holding a baby, while the husband entertains their baby with a rattle.

Two weeks later, the rival child will be fully grown. Upon getting a visit from one of the parents, the player will be taken to the couple's house, where the parents and fully-grown child are waiting happily. The father announces that their child has grown up, and wants him or her introduce themselves to the player. At this point, the player will be able to socialize and befriend that rival child.

The rival children are:
 * Angel - Tom Nook and Sable's daughter
 * Charlotte - Digby and Pelly's daughter
 * Georgia - Leif and Reese' daughter
 * Hartmut - Ethan and Celeste's son
 * Jessica - K.K. Slider and Labelle's daughter
 * Kayden - Rover and Mabel's son
