18 Years

Emi had been best friends with Zöe since she was 5 and Zöe was 6.
Emi went over to Zöe's house once, when she was 6, and met Zöe's brother, Joe. She then managed to gain a baby crush on Joe which then made her baby crush develop to nearly love in 18 years.
23. That's how old Emi and Joe are now. Zöe and Emi are still best friends and Emi has told Zöe many times of how she much she likes Joe.
Emi attends a Sugg Holiday Party one day at Zöe and Alfie's flat. They've hung up a mistletoe and Emi sees Zöe and Alf share a kiss, just making her even more sad that she's still too shy to tell Joe how she feels.

Note: since I wrote this description on my phone and I wrote the story on my laptop, there will not be accents on Zöe's name like so here.
