U have been best friends with Zack since kids and are still friends to this day. Ur both in ur 20s and Zack got married to someone but..they tried to have a kid so many times but failed. Zack was upset about it and so was his wife. He just wanted to give his wife the kid she wanted or she would leave him

he got an idea to ask you to help him but it wasn’t the best idea…

one night while he went over ur house and knocked on ur door.
