The happy rivals who used to bicker all the time are forced to become parents without any pain, and frantically begin a chaotic daily life of protecting their cub. The little milk ball is irresistibly cute, the elders of both families all become baby-protecting maniacs, and they join hands to overturn a conspiracy. One adorable baby, one fate across time and space, begins a high-energy and hilarious healing journey of being pampered by everyone.
