The weight of "what ifs" is a heavy thing to carry, especially when the love never actually died. After a decade of working in the UK, Lena finds herself back in Bangkok, only to be thrust into a high-stakes medical environment where she must work with her first love, Dr. Miu. ​Miu has built a new life, yet the magnetic pull between them remains. Amidst sterile hospital corridors and a tension-filled reunion, they are forced to confront years of suppressed memories and a connection that time and distance couldn't fully erase.
