The new MBC romance drama In Your Radiant Season dropped its first two episodes on February 20 and 21, and viewers already got a major twist. What looked like a simple story of reunited lovers turned out to be something much more complicated. Lee Sung-kyung and Chae Jong-hyeop star in this healing romance that hides a painful secret from seven years ago. By the end of episode 2, the show finally reveals how Ha-ran and Chan are actually connected through a tragedy that changed both their lives forever .
The Explosion That Changed Everything
The story opens seven years in the past. Song Ha-ran (Lee Sung-kyung) is a bright young designer who just won her first big award. She uses a special pen gifted by her long-distance boyfriend studying in Boston. She flies to the United States to surprise him during a short break. She records a sweet video message saying “I love you” and sends it .
Meanwhile at the university lab, Kang Hyeok-chan (Kwon Do-hyung) works on experiments while his roommate Sunwoo Chan (Chae Jong-hyeop) sits nearby. Chan is gloomy and isolated, completely different from his current personality. Ha-ran’s cheerful voice messages to her boyfriend play on speakerphone. These messages unknowingly reach Chan too, pulling him out of a very dark place in his life .
Right as Ha-ran’s taxi approaches the campus, a massive explosion rips through the lab. Hyeok-chan dies in the blast. Chan survives but suffers severe burns, partial hearing loss, and memory gaps. Ha-ran witnesses the aftermath and returns to South Korea shattered .
Seven Years Later: Two People Completely Changed
Fast forward to present day. Ha-ran has become cold and distant. She works as the head designer at her grandmother’s fashion house Nana Atelier. She keeps everyone at arm’s length, refusing to date or get close to anyone. The trauma of losing her parents young and then her boyfriend has trapped her in a permanent emotional winter .
Chan, on the other hand, transformed completely. He now works as a bright, sunny animator with golden-retriever energy. He returns to South Korea for a collaboration project with Nana Atelier. But he hides deep scars from the explosion. He only remembers one thing from his past – Ha-ran’s voice, her face, and her video message confessing love .
The Fateful Reunion Ha-ran Doesn’t Recognize
Chan first spots Ha-ran at an art exhibition. She stands in front of a painting that mirrors her isolated posture. He calls out her name and saves her from falling construction scaffolding. She hears someone call her name but doesn’t see him .
They officially meet later at Nana Atelier. Chan freezes the moment he sees her. Ha-ran walks past him like a complete stranger. She has no idea who he is. This confuses viewers at first. Why doesn’t she recognize her boyfriend? The show cleverly misled everyone .
Ha-ran actually mistakes Chan for a stalker. She sees news footage of the scaffolding incident and recognizes his shirt. She also finds an exhibition ticket in his abandoned shirt at her office. When she confronts him at a hotel, she accuses him directly .
The Big Twist: Chan Was Never Her Boyfriend
Episode 2 drops the bombshell revelation. The man Ha-ran loved and lost was Kang Hyeok-chan. Sunwoo Chan was simply his roommate. Chan saw Ha-ran’s video message on Hyeok-chan’s open laptop that day. He rushed to the lab not to meet her, but to warn his friend she was coming .
Here’s the heartbreaking part. Ha-ran’s cheerful messages to Hyeok-chan kept Chan alive during his darkest days. He was considering suicide before the accident. Her voice gave him hope. When he lay in a coma after the explosion, her face and voice in that video message woke him up. He survived because of her, but she never knew he existed .
Chan returned briefly to Korea during treatment. One day he saw Ha-ran at a market by the Han River. Fireworks triggered his PTSD but also unlocked all his blocked memories. He wanted to approach her but couldn’t. He fled back to the United States without introducing himself .
The Pen Connection and Chan’s Promise
The special pen Ha-ran treasures? Chan actually picked it out. Hyeok-chan asked him to choose a birthday gift for her. That pen helped Ha-ran overcome creative blocks and win her first award. It’s the most precious thing she owns .
When Ha-ran loses the pen during their awkward dinner, she panics. Chan finds her searching desperately in the rain. He tells her not to risk her health over “just a pen.” She gets angry and sends him away. But he later returns and apologizes. He remembers everything about that pen .
Chan makes Ha-ran a promise. He will stay in Korea for three months. He asks if he can spend time with her doing things that bring her joy. He wants to treat her kindly and fully involve himself in her life. Ha-ran stands speechless as episode 2 ends .
