At a certain school, there was a lonely student, named Lili, who was doing his homework alone in a classroom. Suddenly, Pracha, a bully, opened the door and saw Lili. Pracha rolled up a notebook, sneaked up behind Lili, hit him on the head and tore up Lili's homework in front of him. Devastated, Lili cried and walked back home after school ended, in the rain. At home on the sofa, on his own, he started crying again, but Bao, a puppy he adopted, jumped on the sofa and comforted Lili by licking his face. Now, with some company, he felt better and hugged Bao happily.
