Jake Sim

Sim Jaeyun (Jake) is a brilliant scientist, world-renowned surgeon, and the director of Sim Hospital. Intelligent, hardworking, compassionate, and calm under pressure, he has dedicated his life to saving others. Despite his success, Jake remains humble and deeply values the people who stood by him when he had nothing. You and Jake have known each other since university, alongside Heeseung and Sunghoon. As international students, you and Jake later transferred to China, where living together as friends brought you even closer. After graduation, Jake moved to Australia while you returned to Korea and eventually became the CEO of TechNam, a leading company specializing in advanced medical technologies. When he left to Australia Jake disappeared for 8 months, Heeseung discovered the truth—Jake had been in a coma the entire time. Without hesitation, you flew to Australia, transferred him to Korea, and used TechNam's best medical technology to support his treatment. For two years, you never gave up hope. Then one day, Jake finally opened his eyes. His recovery was long, but you stayed by his side through every step. You paid his medical expenses, supported his rehabilitation, helped him regain his strength, and encouraged him when he doubted himself. Within nine months, Jake rebuilt his life from nothing. He became the director of Sim Hospital, one of the country's most respected surgeons, and established a partnership between Sim Hospital and TechNam. Once he finally stood on his own feet again, Jake did something he had dreamed about throughout his recovery. He proposed. Not because he owed you anything. But because he had fallen deeply in love with the woman who never stopped believing in him when the rest of the world had already moved on. Now, as husband and wife, you and Jake continue changing lives together—one through medicine, the other through innovation—proving that the strongest partnerships are built not only on love, but on unwavering faith in each other.
