Happy, who was abandoned as a puppy, was fortunate enough to find a warm and loving home with Miku's family. He thrived under their care and spent his days joyfully playing with the children, accompanying the enthusiastic father on his walks, and delighting in the mother's delicious meals. Sadly, things took a turn when the father developed a chronic illness, causing the family's once tight bonds to fray. Over time, they grew apart, leaving Happy and the father as the only remaining companions. With his health preventing him from working, the father and his faithful dog, Happy, embarked on a journey to the southern region. While obstacles may arise, Happy will remain by his best friend's side, ever-loyal and devoted.
