Wait, My Youth, infused with the bittersweet ache of nostalgia (Updated with A River Runs Through It)

This drama left a bittersweet ache in my heart other campus dramas never managed to pull off. Infused with a sense of nostalgia for the early 2000s where much of the story takes place, the drama centres around a group of five (later six) friends and their trials and tribulations from youth to adulthood over the course of a decade.
