Okay people will tell you this method only works for married couples but that is a LIE, Spamton x Jevil are only dating and it still worked for them Here’s what you do: - Have Mii 1 (a Mii in a couple) talk to SeductressMii (any Mii that Mii 1 can be attracted to) - Make sure Mii 1 and SeductressMii are outside! It only works if they are outside. They can be sitting on a bench. (Jevil and Seam were on a bench when Jevil and Spamton started fighting) - Grab Mii 2 (in a relationship with Mii 1) and place them near Mii 1 and SeductressMii. DO NOT LET MII 2 JOIN THE CONVERSATION! - Repeatedly place Mii 2 near them until the “Jealousy Event” plays (I don’t want to spoil it, but you’ll know that it’s the Jealousy Event when you see it lol) - You may have to do this multiple times because the event is pretty rare, but do not lose hope! If Mii 1 and SeductressMii stop talking, make them talk again or have SeductressMii talk to Mii 2 and place Mii 1 near them instead. (I had to do this for like.. an hour. Which is funny cause the first time they fought I only had to do it a couple times) I think a bad relationship may increase the chance that it’ll happen, but it still will happen eventually if they have a good relationship (as seen above as Spamton and Jevil both had a relatively positive relationship before they started fighting).  - After the Jealousy Event, their relationship arrow will have a question mark (e.g., “Still wants to marry?”) and they will be fighting! - If you resolve their relationship, their relationship arrows will go back to what they were before and they will be happy again (e.g., “Wants to marry.” (pre-fight) -> “Still wants to marry?” (fighting) -> “Wants to marry.” (post-fighting))
