House Husband? Try Supreme Immortal (DUBBED) - 集 1

Logan Bale, an immortal who has walked the earth for a thousand years, fulfills a dying promise to his disciple—to protect his family for three years. To honor that vow, he marries his disciple's granddaughter, only to be met with her family's scorn and cruelty. Yet undeterred, he endures their contempt with quiet resolve, holding fast to one promise of his own: to walk away the moment those three years come to an end.
