Cassette Tape.A man visits his childhood home for the first time in many years after hearing his old friend, Tanabe Kouichi, is getting married. He returns to the room where he spent most of his boyhood, happy to see it's still the same as he left it. Further exploration of his old room leads him to find a cassette tape in his desk labeled, "What Happened Today". Always a fan of scary things and wondering if it still works, the man puts the tape in a player and presses play. He hears his boyhood voice and he remembers that as a child, he would record his daily life on cassette tapes. On the first entry, February 12, he talks about playing baseball and winning despite Onedera, a rival player, being an excellent pitcher. On February 23, he talks about Tanabe's birthday party at his house and receiving gifts from all his friends and admits he's a tad jealous. The man finds it coincidental hearing his boyhood self talk about Tanabe. On June 7, his boyhood self talks about being able to do anything in his dreams, including trampling over people, being invincible and crushing buildings. On August 8, he talks about his mother walking a lot and wanting to talk to her, but deciding not to. Suddenly, the voice on the tape sounds older. The man assumes he made this during middle school. On October 15, the voice talks about loudly yelling in class four times but no one was there to scold him. On January 9, the voice claims to have heard something rattling in a box and that he's happy. On February 16, the voice says he felt something, like fingers wiggling. He told no one. On April 11, the voice says he said good morning to an old man at a jagged park only for him to say, "No it's not." The man gets confused hearing that; he doesn't recall doing or even saying that. He can't understand what his younger self is saying anymore and the stories are starting to become more and more nonsensical and surreal. On February 23, the voice talks about how Tanabe and Tanabe were birthday plastic modeling at Tanabe's house. On June 7th, the voice says it thought it would stay the same if it stayed a long time, but when it looks closely lately it can see cracks and wondered why it was shaking. Maybe that's it. The man suddenly hears his own older voice. On April 7, the voice says it's a great day at work and how he can be happy about anything. But don't laugh, you'll make it shake. Then the man becomes horrified when he hears the voice talk about Tanabe's wedding tomorrow and then it starts rambling about taking a stick and beating Tanabe with it just like what it did to the old man in the jagged park and then the tape stops. Not wanting to hear any more, the man takes off the headphones. That's when he realizes they aren't even plugged into the cassette player. The wedding the next day was as exciting as can be...
