Step one:Make sure they are friends. Step 2:Do the blind date thing.(that can take a long time) Step 3:When one of the miis says "Why did blah blah want me to go out with blah blah?" 3 words.Always.Say.Perfect match. Step 4:Wait until the mii expresses it's feelings.If the mii says yes,you are sucessful.If it says no,sorry bub didn't work. Hope it worked :)
