According to a detailed wedding interview published by Inside Weddings, the pair remained friends throughout their school years.
However, their friendship did not immediately become romantic.
Rachel recalled an incident during their junior year of high school when they were spending time with mutual friends.
Although there appeared to be some romantic interest, neither pursued a relationship at the time.
They continued their friendship and eventually began dating later.
After becoming a couple, Sebastian realized relatively quickly that he wanted to build a future with Rachel.
According to their wedding interview, he began considering marriage approximately five months into their relationship.
The connection continued as Joseph-Day developed his professional football career in California.
How Did Sebastian Joseph-Day Propose to Rachel?
Sebastian Joseph-Day proposed to Rachel Lucosky during a surprise photography session in Malibu, California.

However, pandemic-related travel restrictions complicated his efforts to bring their relatives from Pennsylvania to California.
Joseph-Day eventually developed an alternative plan involving a professional photoshoot.
During the session, the photographer arranged for the couple to stand back-to-back.
When Rachel turned around, she discovered Sebastian kneeling with an engagement ring.
She accepted the proposal, and the couple began planning their wedding.
Approximately one year later, Sebastian arranged another special birthday surprise involving a private helicopter tour of Los Angeles.
The gesture became another memorable moment in their relationship.

In November 2019, he traveled to Los Angeles alongside his wife to watch Sebastian start an NFL game in person.
