The plot revolves around this technology/device that lets you create an alternative ego of yourself(a better version) when you put on the earpiece. The mc essentially works as an agent that deals with people that get too dependant on the earpiece and become corrupted. Iirc the name of the guy who made the earpiece is yuri(ironically enough I saw people saying that the author's previous works were yaois, specially with tragedy tags lol) The artstyle was very pretty and I also really liked the plot.Very sci-fi action leaning into ethical questions with a hint of bromance.It used to be on my list but well it's gone now
They're so adorable I love this manga (つ≧▽≦)つ
