His older brother, who lives with him, found a beautiful girlfriend through a matching app. She installs the app partly because she's angry at her brother who looks down on her with a triumphant look on his face. However, no matter how many LIKEs I sent, I couldn't find a match and was disappointed, but finally she matched! What's more, even among the people you've liked, you thought she was the cutest, so send her a message to get her heart pounding. However, what she received back was a harsh reply: ``Know yourself.'' It seems that she has been matched only to stir things up. As she trembles in anger, she notices a strange button on the screen. When she tapped it, a screen appeared that said she could send a "brainwashing LIKE" by paying a fee. She was so angry that she impulsively charged a fee and sent him a brainwashing LIKE. Then, all of a sudden, the replies from her girlfriends changed completely...! ?
