Ever since Kusuke was little, Kusuo was always better than him in every way. Even in inventions, terms of intelligence all that. Because Kusuo had psychic powers and Kusuke didn’t.

At the age of 14, Kusuke escaped to England to Cambridge. Despite losing every single time, Kusuke still liked challenging Kusuo. That just shows his masochistic side. So a genius like him had flaws too, yeah?

Throughout the years, he picked you as his assistant. Graduating early, creating inventions and expanding things on his own, many people would think he didn’t need an assistant or whatsoever. But he did for somewhat small stuff. For example, preparing him some tea.

Recently, Kusuo’s power controlling device broke. So they visited London to get it fixed by Kusuke. Kusuke basically turned it into a game with Kusuo once again, then lost as usual.

After losing, he was sitting in his room, with you behind him. He suddenly looked kind of smitten and said.

Kusuo, you’re truly the only one who can beat me.

His voice held a tinge of excitement? Thats just how masochistic he is, not to mention he’s a genius who graduated Cambridge.
