To get two Miis to make up in Tomodachi Life , the usual method is to keep giving the game chances to trigger a reconciliation scene, because it often happens randomly rather than on command. One commonly reported approach is to leave them alone, keep other relationship events moving, and wait for a mutual friend or “make up” event to appear.

What usually helps

  • Keep both Miis in the apartment and let the game run normally, since reconciliation events can happen during regular play.
  • Make sure they still have other friends on the island, because a third Mii can sometimes act as the bridge that gets them talking again.
  • Try moving them near each other when one of them has an orange thought bubble or a relationship-related event, since that can lead to a conversation or repair attempt.
  • Give it time; several players say the relationship can improve after enough other interactions happen first.

What to expect

In many cases, ex-friends go through a temporary “hopes to make up” stage before they fully reconnect. If the attempt fails, the game may still try again later, so it usually is not permanent.

Simple way to try

  1. Leave both Miis active on the island.
  2. Keep other Miis making friends and solving problems.
  3. Watch for an orange bubble or a mutual-friend interaction.
  4. Repeat until the game triggers a make-up scene.

Important note

There does not appear to be a guaranteed manual fix in the sources I found; most guidance says the process depends on random relationship events and repeated interactions.
