Tada Shiawase na Isekai Kazoku Seikatsu, Tensei Shite Kondokoso Shiawase ni Kurashimasu

Susumu Araki spent his life as a devoted and hardworking father of two, pouring his energy into providing for his household. Despite his relentless efforts, he was ultimately met with rejection and emotional distance from the very family he sought to support. His quiet life of unappreciated dedication takes an unimaginable turn on his fiftieth birthday when he suddenly loses consciousness, leaving behind a world where his sacrifices went unrecognized. He awakens not in a hospital bed, but in an entirely different world, reborn as a newborn baby. Now bearing the name Tidus, he is given a miraculous second chance at existence. The painful memories of his past life—where devotion yielded only estrangement—serve as a powerful catalyst for change. He refuses to let history repeat itself in this unfamiliar realm. Armed with the maturity and hard-earned wisdom of a fifty-year-old man trapped in an infant's body, Tidus makes a solemn vow. He is determined to forge a life completely free of regrets, dedicating himself to building genuine bonds with his new family. Rather than repeating the mistakes of his previous existence, he sets out to cultivate a truly fulfilling and joyful life alongside those who now depend on him.
