- "I want to break up with [Mii]."
- — Mii, Tomodachi Collection
Breakups first occur in Tomodachi Collection, when a Mii's relationship with a sweetheart is low. The Mii states, "things haven't been going so well with [islander]" the player can then decide whether the Mii should move on or try to work things out.
If the player decides that the Mii should move on, it triggers a cutscene in the cafe where the Mii breaks up with their sweetheart by saying they are tired and want to be friends again, while leaving both Miis depressed.
If the player decides that the Mii should try to work things out, it will trigger a cutscene in the other Mii's apartment where they stand facing each other with the lights off and a clock ticking in the background. If the Mii succeeds, then they will hold their hand out as the lights turn on and suggest trying again as the other Mii responds in agreement. If it fails, the couple will crouch down, look at the floor, clutch the sides of their heads with both hands and rapidly shake their heads as a gong sounds. This results in the couple having to break up.
- "Things aren't going so great with me and [Sweetheart/Spouse]..."
- — Mii, Tomodachi Life (US)
Breakups are used once again in Tomodachi Life, functioning almost exactly as its predecessor. In this game, however, the Mii breaking up will say their feelings have changed, instead of they are tired.
In Life, it is also possible for a Mii to confess their love to a Mii who is already dating. The dating Mii may accept the confession and leave their sweetheart for the confessor, with the former sweetheart gaining a sadness meter. There will be no breakup afterwards. This event is quite rare and usually only happens when the sweethearts have low relationship statuses with each other.
If a married couple breaks up, then upon visiting them, they will be in a depression. The one who broke up says, "Maybe we aren't meant to be together. At least not right now. Breaking up with your sweetheart is really painful." The other says, "My heart has hurt since we broke up. It's not heartburn either. What am I supposed to do now? I feel so lost."
If the two Miis were married, their house at Mii Homes will be completely demolished, leaving a vacant spot in its place until a new married couple fills it.
Miis will not divorce or fight if they have a baby in their home, making babies the only surefire method of preventing breakups (they may fight, but not with their spouse).
In addition, if the player goes to the apartment of the Mii that was broken up with and tap the icon, they will say, "Will I ever recapture those happy times again?" and then displaying a cutscene showing moments when the two Miis were together. There are two versions of the flashback, a long and short version. The long version occurs if a Mii's sweetheart leaves for another Mii. The short version is if the two Miis that were sweethearts broke up after failing to work things out or if the player tells the Mii to simply move on.
The first scene is on the beach. It starts with the Mii running away from its sweetheart as they chase each other along the water, then they splash each other. The male Mii wears swim trunks and the female Mii wears a bikini. This is followed by the "tropical beach" photo of them.
The next scene is the sweethearts playing tennis. After a few hits, the Mii hits the ball out into the distance, leaving their sweetheart to giggle as it looks on confused. This is followed by the "Bokeh" photo of them.
The next few scenes take place in the Mii's apartment. The first is the two in a back-and-forth conversation saying they love each other. This is followed by the "holiday" photo of them; then the Mii tells a joke to the sweetheart using a random item, but the sweetheart wasn't listening.
The last scenes take place shortly after the breakup, first the Mii playing tennis alone before giving up. This is then followed by the "cherry blossoms" photo of the Miis. The final scene of the flashback is the Mii sitting on the beach, staring into the sunset alone.
If the player chooses to have the Mii move on or if they fail to work things out, the tennis scenes are absent as well as the photos.
Another version of the flashback can occur after the main flashback is played. Upon tapping the Mii's thought bubble, it will say, "I can't stop thinking about all those happy times we had..." and the "I love you" scene of the flashback will play, but with the Miis repeatedly adding "really" to their conversation. Alternatively, the joke scene may play instead, telling several jokes until the player leaves.
Cutscene Break Up
Upon entering either of these places, there's a chance a cutscene will automatically begin with the couple sitting together. The first Mii will say "We had a good run. Thanks for everything." or "Thanks for the great memories." Then, the other Mii will say "No, thank you." Then, a text box will read "[Mii 1] and [Mii 2] are back to being just friends." Afterwards, the view fades to white and the player is taken back to the island. If this positive breakup occurs, neither of the two Mii's will be depressed. This type of breakup can be avoided if the player does not enter any of the hangout areas or only enter the areas when a couple is not there at all.
Interestingly, the Miis who broke up this way will not have their partner listed as Ex-Sweetheart/Spouse. Instead, they will be listed in friends.
Getting Back Together
It is possible for Miis to get back together, depending on their relationship status. The procedure is similar to the way a Mii would confess their love, with a few differences. As melancholic music plays, one of the ex-lovers will admit they cannot stop thinking about the past with their lover, and requests that they get back together. Should the player agree, the player will relay their message to said love interest. The love interest will then ask in surprise of they really said that, before deciding they will think about it.
The scene that follows will always take place on the beach, and has a procedure similar to a confession. The Mii will ask if they want to give the relationship another try, and if it all goes well, the two Miis will return to being sweethearts, and, if they were married, their house will be rebuilt. Any Age-o-matics that were used on either Mii will also return.
If not, the Mii will sink to the ground sadly as it becomes sad and heartbroken, but they will not gain sadness and their relationship will not decrease. Sometimes the ex-love interest would immediately refuse and ask the player to ask the Mii if things are going okay, putting the Mii in sadness. It is possible for an ex-sweetheart to express this feeling even after their former love interest became involved with a different sweetheart.
- Since breakup requests are random and in some cases unpredictable, with no way to back out once the player taps the Mii's thought bubble, players should check the Mii's Relationships with either the L or R buttons if they want to prevent a breakup. In most cases, if the relationship level is very low (such as the relationship level being displayed as "Not getting along") by a Mii that isn't in a fight, the player should return to the island and save immediately, then re-enter and select "Work it out". If the couple fails to resolve things, the player should close the game entirely without saving, then re-enter and try again.
- In addition, it is hard to tell if the couple can work things out or not.
- It is entirely possible that a couple with low relationship levels will divorce off-screen while the game isn't powered on, without any orange problems indicating their desire for a divorce beforehand. The day following the divorce, only one Mii will be depressed about the divorce.
- If a sweetheart couple manages to successfully work things out, both statuses will become "Very much in love" (will revert back or go up depending on their previous status before a breakup). However, if a married couple successfully work things out, the statuses will remain the same until they have a chance to breakup again or ask the player about the relationship with his/her partner.
- The music over the cafe's radio during the breakup cutscene is a somber, lower-key remix of the theme from the Compatibility Tester if the player gets an 80-89% rating.
- If a Mii wants to reconcile, the background music played is a harp remix of the gentle bell theme played when he/she has feelings for someone.
- Sometimes, when a Mii breaks up with his/her sweetheart, the Mii will not get depressed if he/she is involved in a fight or sick.
- Sometimes, when a Mii takes a photo, he/she might capture a female going out with her sweetheart in the café, and the ex-sweetheart will be sad and jealous.
- When two dating or married Miis have a huge fight, they could break up autonomously if not sorted out.
- In the Japanese version, a Mii's spouse can be stolen by another Mii if that Mii has low relationships, leaving the other Mii in sadness and their house destroyed. In Western versions, nobody will fall in love with the married Mii.
- If the Miis were sweethearts after breaking up, the Mii asking will get half a bar of sadness. If the Miis were married, the Mii asking will get three-fourths a bar of sadness.
- In addition, the other Mii will always have a full bar of sadness.
