All right, so I was playing MySims, and my Sim, Sam (She is goth), seems to be in 사랑 with Goth Boy! So let's start-
1. Whenever 당신 hit "Be Nice", your Sim either blows a 키스 또는 gives a hug to the Sim 당신 want to be nice to.

2. Your Sim blushes when receiving a 키스 from the Sim they are in 사랑 with.

3. Your Sim always encounters them when they are outside.

4. Your Sim always hangs out at their place.

Do they 사랑 me back?

5. That Sim blushes upon receiving a 키스 from your Sim.

6. That Sim gives 당신 a lot of hugs and kisses.

7. That Sim wants to be in whatever your doing. (For example, if Mary, my friend's Sim and possibly Travis' crush, was having a dance-off, and Travis, Mary's crush, came along, he will 가입하기 her. With GB and Sam it's always séance cuz they're spooky)

8. They 가입하기 당신 when you're in the fountain.

9. They hang out around your house and/or workshop.
