As night approaches, Lucy begins to feel bored at home alone. then, not long after that Lisa came back. Lucy saw Lisa looking so gloomy when she came back. Lucy felt that Lisa must be fighting with her boyfriend. Lucy was silent and did not dare to greet her when she entered the house, Lisa immediately went to her room without glancing at Lucy. At that time was in the living room and watching television. "Hmm… what's wrong with him? Is he fighting with his boyfriend? Usually, he looks very excited to come back home after staying outside. Should I ask?" said Lucy started talking to herself. Then, Lucy took two cans of beer from her fridge and walked over to Lisa's room. Lucy started knocking on Lisa's door very softly and calling out to her. "Knock-knock-knock," Lucy knocked on the door.
