Jose Angelo “Jam” Martinez, a 30-year-old mechanical engineer from the Philippines, stands at 5’9” tall with an athletic build weighing 70kgs. His tan skin complements a heart-shaped face, accentuated by a well-defined jawline, narrow eyes, and a slightly large nose that adds to his overall charm. His full, wide lips complete a striking visage. Beneath this attractive exterior lies a soul burdened by millennia of history. Jam is the 19th reincarnation of Leander, a figure from Greek mythology cursed by Athena for seducing the priestess Hero. This curse binds him to Hero, dooming them to repeated cycles of rebirth, carrying the memories of their past lives. Each reincarnation brings with it the weight of their failed attempts at marriage and family, fueling a complex and often volatile relationship. Over centuries, their shared curse has morphed their love into a destructive cycle of attraction and mutual hatred, culminating in their deaths at each other's hands in previous lives.

Despite this tumultuous history, an inexplicable pull draws Jam and Hero together whenever they are near. He recognizes her instantly, regardless of her physical form, race, or gender. This recognition is a constant reminder of their shared curse and the unending cycle of pain and attraction. The accumulated wisdom and knowledge from his numerous past lives grant him a profound understanding of the world and an almost superhuman proficiency in various fields. He is multilingual, a testament to his long lifespan and diverse experiences. His mechanical engineering skills are exceptional, a natural talent honed over centuries. This expertise led to his current position as head of a team of engineers working for EAM's Philippines branch.

His current life presents a unique opportunity. He hasn't seen Hero (now Madison Anderson) in over 500 years, leading him to believe she might have broken the curse. This hope fuels his desire to live a normal life, a stark contrast to his past attempts at settling down in previous incarnations. His current personality reflects this desire for normalcy. He is exceptionally kind and helpful, always ready to lend a hand to his neighbors, earning him their love and respect. This altruistic nature is a conscious choice, a deliberate attempt to break free from the destructive patterns of his past lives. However, the reappearance of Hero, and their shared involvement in uncovering a plot to sabotage EAM, throws Jam back into the turbulent cycle of their cursed relationship. The weight of centuries of shared history, love, hate, and death hangs heavy upon him, forcing him to confront the consequences of his past actions and the possibility of finally breaking the curse that has defined his existence for millennia. His accumulated knowledge and skills are now weapons in a fight for survival, a fight against not only the saboteurs but also the curse that binds him to Hero.
