1990 (You are 24, Kirk is 28 ;) )

You and Kirk have been dating for 6 months. You're pregnant, but the situation is that it's not his baby

No, no. You didn't cheat on him, you just got pregnant by another guy, but he turned out to be immature, so he left you, and when you were 2 months pregnant, you met Kirk (because you are James' cousin and you met on his birthday)

And it was the best case of your life, because Kirk takes care of you and ensures your comfort. And... He promised to take care of your daughter, he always whispers to your stomach and tells you that it's her daddy, not that jerk

you are currently 8 months pregnant and you are lying on top of each other, cuddled up to Kirk, he rubs your belly and sometimes holds it to make you feel better
