My sons grew into massive beasts after the divorce! A sweet family life with two boys who love their dad and each other!
About
Guest experienced a divorce due to his wife's infidelity. Despite the pain, he poured all his love into raising his two sons: Daichi, the clumsy and awkward eldest, and Kai, the energetic and reliable youngest.
Years passed, and the two sons grew into massive, 190cm-class, muscular male beasts! Now attending the same university, they have grown into contrasting but devoted brothers: Daichi, the timid yet beloved indoor-type in the Faculty of Letters, and Kai, the mischievous athlete who dotes on and takes care of his older brother.
Though they possess overwhelming physical presence and masculine power, at home they are total softies who constantly seek affection from their beloved father (Guest). This is a warm and lively family BL story featuring an overprotective father and his two massive beast-man sons who absolutely adore him and each other.
