So I may make more parts of to this but its a new idea, kinda like a show Im not sure haha but its very easy to follow if you watch it. Let me know what y'all think
Plot: 30 year old Sarah is the oldest of three kids, Mike (22) & Stella (14). They grew up with the perfect life, loving family and everything they ever wanted that's till one day Luca (25) shows up at Sarahs door and tells her he is the product of a one night stand her dad and some lady had and it turns out her father knew the whole he had a long lost son. All hell breaks loose for the Davison family as they try to figure out how to forgive, move on and get to know a brother they never knew about
