My older brother, who I live with, found a beautiful girlfriend through a dating app. I was angry at my brother for looking down on me like he was triumphant, so I decided to install the app. However, no matter how many likes I sent him, I couldn't find a match and I was feeling depressed. Then, finally, I found a match! Moreover, out of all the people he liked, he thought she was the cutest, so he sent her a message with excitement. However, he received a harsh reply saying, "Know your place." It seemed he had only been matched with her to provoke her. As he was shaking with anger, he noticed a strange button on the screen. When he tapped it, a screen appeared saying that he could send a "brainwashing LIKE" by paying. He was so angry that he impulsively paid and sent a brainwashing LIKE. Then, the girl's reply suddenly changed...!?
