In the final episode of MBC’s “In Your Radiant Season”, Lee Sung Kyung’s character Song Ha Ran doesn’t just get a happy or sad ending—she gets a truth so heavy it reshapes her entire understanding of love and loss. Seven years after a tragic accident in Boston, she finally learns the real story from Cha Su Jin (Lee Joo Yeon) in a hospital showdown that leaves her stunned, heartbroken, and quietly grateful all at once.

What happens ‘In Your Radiant’ finale between Song Ha Ran and Cha Su Jin

Detail	Info
Where the truth surfaces	At a hospital where Cha Su Jin (Lee Joo Yeon) works as a returning trainee doctor.
Trigger moment	Ha Ran finds Sunwoo Chan’s shattered drawing pad and a note reading “Trial version ended,” then remembers a cryptic remark Su Jin once made and goes to confront her.
Main revelation	Su Jin explains how Sunwoo Chan kept pretending to be her late boyfriend Kang Hyuk Chan in online chats, which became a key reason Ha Ran fell for Hyuk—and how that same message bond indirectly triggered the accident that killed Hyuk and left Chan injured.
Cha Su Jin’s role	Su Jin blames Chan for the incident, which makes him vanish and suffer alone, and she finally owns her part in keeping the truth hidden.

Why ‘In Your Radiant’ moment hits so hard?

For years, Song Ha Ran blamed either fate or her own choices for the pain she carried. When Cha Su Jin walks her through the hidden chain of events—starting with a simple laptop swap and ending with a fatal explosion—Ha Ran realizes Sunwoo Chan (Chae Jong Hyeop) wasn’t just a playboy but someone who tried to shield her from guilt, love, and trauma at his own expense.

The finale doesn’t give her a clean, fairytale wrap‑up; instead, it hands her a bittersweet mixture of clarity and forgiveness, leaving their romantic future open‑ended but emotionally honest.
