In The Summer I Turned Pretty season 3, Steven quits his job to work full-time on his startup.
This development occurs in episode 10, “Last Year,” during the season’s Paris storyline. Steven’s professional decision is connected to Denise, his office co-worker, who becomes involved in the startup and later hosts Jeremiah temporarily.
The choice is part of the season’s broader focus on characters moving from college and early employment toward adult careers. Steven and Taylor also move in together and host a combined Thanksgiving dinner with Jeremiah, showing how their personal and professional lives are changing at the same time.
The startup should not be confused with Adam Fisher’s firm. Jeremiah works at Adam’s firm during the wedding-planning storyline, while Steven leaves his job to pursue his own business with Denise.
