3 years later

Backstory:
My name is Y/N Y/L/N
My dad left me when I was only a month old
Not long after my mom met Eric Lamonsoff, he raised me like his own daughter, but I never felt brave enough to call him dad even though he is a dad to me
My mom and Eric got married two years later and was expecting my half-sister Donna and then later on then had my half-brother Bean
Five best friends were reunited for a funeral and a weekend at the lake house
What happened after?
Will a romance spark between Y/N and Greg?
What will life be like for them?
