JAA Series no. 1 "Angel in Disguise"

Everyone might perceive her life as idyllic, but deep down, she feels it's far from being truly fulfilling or perhaps even luxurious yet torturous. Possessing all the trappings of luxury, she yearns for a sense of purpose. Her heart remains unfulfilled due to the lack of genuine affection from her family. In a moment of vulnerability, she turned to her late mother, who gave birth to her, on a fateful night. With tears in her eyes, she made a heartfelt plea, knowing the impossible, "Though I can't be with you, maybe an angel could visit me? I don't know how long I'll endure this solitude." Suddenly, a soft knock echoed through the room, catching her off guard. Who could this mysterious visitor be?
