This might be a silly idea but I think it would add something special to the game in the future.
Basically i propose emotes that couples can use. Maybe like a cuddle emote where you hug each other really close. A kiss emote, a holding hands emote. etc.
And maybe set it so they only work on ppl on your friend list (so the ppl have to have each other added).
Given the number of couples that play this game, i think it would be beneficial.
Further, it would help guys convince their GFs to play with them which will not only benefit the population but also would help keep players in the game (since when you have a loved one to play with it prob makes the game more special)
