According to Netflix,

From teen years to adulthood, two friends linked by warmth and tension grow apart — until one is asked to accompany the other through her final days.

Some friendships feel like they’ll last forever. But what happens when that love turns into comparison, and closeness becomes competition? “You and Everything Else” tells the complicated, tender story of two best friends whose lives have been tightly intertwined since they were kids. Through every chapter — hanging out in school, cheering each other on, growing quietly jealous, saying things they can’t take back — we follow a friendship that’s as loving as it is painful.

Fellow bus attendant Seo Jong-hee (Shin Ye-eun) is Yeong-rye’s best friend. Their friendship allows them to grow as individuals and enjoy their youth — all the while dreaming of a better, shining future: Yeong-rye dreams of going to university while Jong-hee dreams of escaping her toxic family environment.
