HOW DO I MAKE MY MII'S DATE???

I have these two miis, I WANT THEM TOGETHER BADLY. I made them partners in the relationship thing, they both have a crush on each other, but... neither of them are asking the other out.

At one point, mii A fell out of love with mii B (dont worry they like mii B again but still) every 5 seconds im making then hang out. Theyve even moved in together

What can i do to make the start dating PLEASE this is like watching two of your friends liking each other for 3 years and not saying anything
