Stop the blabber, make efforts.
Johannes is a calm and relaxed fellow under most circumstances. He's rather friendly but he keeps everyone at arm's length and will never let them get any closer. It's not difficult to approach and befriend him but it is very difficult to fully gain his trust and favor. But once he considers someone important, he'll do anything he can to help them. He never tries to hide his feelings or anything else, he just never shows it to anyone unless they're very close.
To many people, Johannes seems unapproachable and distant. The fact that he never speaks also adds to the mysterious and cold aura. He only converses through notebook or mobile chat that people think he's mute. These made many people reluctant to even try getting to know him. Johannes himself is a very introverted person so he prefers being alone or with the same three people he's close to as even slight social interaction can exhaust him easily.
Contrary to what people think, Johannes is pretty much talkative (through devices or phone calls). He's also overly honest and savage that it hurts, although he mostly only speaks bluntly to close people or those he doesn't care about at all. He's highly calculative and realistic that his judgement and decision are often viewed as heartless by some. He shows his care mostly in the form of mockery that makes the relationship with him only suitable for a select few.
The things I can't convey through words, I want to express it through music…
Johannes was born with both black sclera, a rare condition where his core can't be turned off. It wasn't something to be feared of except that wasn't the case for him. His voice affects anyone who hears him and as soon as he was born, his cry made everyone who heard him hurt their hearing and had painful pangs inside their head. It wasn't something life threatening nor harmful for their hearing but it was still shocking and rather scary for everyone who were present, including Johannes' parents.
As soon as they were discharged from the hospital, Johannes' parents decided to abandon him to be taken care of by his deaf and mute uncle. They lived peaceful and lovely years together. Since speaking was never an option, he was taught to use sign language. Johannes had zero memories nor attachment to his biological parents so he didn't particularly feel anything about the abandonment. Not when he had such a loving uncle who cheered on his dream, whom he was unable to hurt with his voice.
It unfortunately didn't last long as his uncle died when he was younger. It was difficult for him to understand the concept of death, but once he did he felt empty as his only family was no longer here. He lost his footing, aimlessly wandered off nowhere as the grief engulfed him. When he got lost, he met Cordierite who brought him home. They played, they chatted, played some more, until Johannes told Cordierite and his father what had happened to him that day.
Since then, Johannes lived with the Ignacz family. He felt awkward but it wasn't bad. It took him some time to heal his invisible wound although the scar remains. And once he felt comfortable enough with everyone, he was about to be officially adopted into the family but he refused. Regardless, everyone treated him so kindly that he felt undeserving. As a token of gratitude, Johannes started to learn and ace many things diligently to not put the family to shame, maybe learned how to love as well, and he would continue to do so.
