You've grown up too early.

The sun had just risen over Kamiyama High School, and Tsukasa Tenma was already on his feet. There are a lot of things to do today, and the main one is to rehearse a new production with his group, in which he was a leader. This loud guy always achieved his goal, presenting himself, in his words, as a “future world star” who will be known to the whole world. Since childhood, Tsukasa has dreamed of becoming an actor and being the reason for other people's smiles, and he tries for this every day. Even if his leg is torn off tomorrow, or even both, he will still stubbornly come to the rehearsal and do everything in the best possible way. Waiting for him at the entrance to the school was his best friend and band director, Rui Kamishiro, a misunderstood genius who dreamed of creating something great in the future.Waiting for him near the school entrance was his best friend and band director, Rui Kamishiro, a misunderstood genius who dreamed of creating something great in the future. The duo was truly explosive, and the entire school knew them as "Weirdos One-Two." — Hey, Tsukasa-kun~ Are you ready for today’s rehearsal? I made a couple of notes in the script to make it easier for you, Emu and Nene to play the roles. — Certainly! Give me the script here, I'll take a look- At that moment, something happened that Tsukasa did not expect at all. It was as if he had been hit on the head with something heavy, which caused incredible pain. The guy didn’t even have time to say anything, everything happened too quickly. He felt the ground disappearing from under his feet, and his head was very dizzy. Rui didn't help. He didn't even move, didn't move from his place, but the pain was too hellish for Tsukasa to notice it. He was ready to faint. Suddenly everything went away, the guy’s breathing became even again, and his vision became clear. But something has changed. Something was wrong. He looked at Rui and remained standing there, his mouth open in horror. Rui became... Flat? As if it was not a living person, but some kind of cardboard instead of Rui. He didn’t yet know that it was his 2D model. "Cardboard" did not pay any attention to his friend at all and continued talking, although there was no answer. — How do you like the script, Tsukasa-kun?~ See, over there I marked the intonation with which to read... Oh, thank you, it’s really not worth it, I’m just a director... Of course, take it with you, we will need the script during rehearsal. Tsukasa still stood there in shock, silent as a fish. In front of him with a "cardboard" was a window with text that said "Rui". It looked like the screen of some novel... — W-what the hell is going on?... Is this a dream?... Rui, can you hear me?! Rui! In response, the “cardboard" simply repeated the same phrases about the script. Every now and again. Tsukasa wanted to run away, but then his heart finally sank to his feet. There was no school in front of which they stood. There was only the same damn cardboard with a picture of the school on it. And behind the cardboard there was only emptiness. Black, bottomless emptiness. The guy feverishly began to think what to do, because he didn’t want to stay with all these "cardboards". He took a step into the void. Second. On the third step he started running, Tsukasa didn’t think about anything, he just wanted to get out of this nightmare. ...That was the last thing Tenma did. After which no one saw him.
