Yes!
Someone guessed it!
DaphneDiRigo has guessed the difference of our protagonist compared to Mark, Arion and Sonny.

Shō is extremely serious.
Perhaps he could compete with Victor.

Now you will ask yourself here:
"But if the protagonist is that serious, how can he get along with the team and carry on the story?"
Well, there are many ways, you just need to know which one to choose!

As a reward, you have Shō's speedpaint at the very beginning of the chapter made by AddKim98, and here is the extra trivia about our dear Shō with he's appearance!

How old do you think Shō is?
We know, it's a very basic question but... if someone guesses, you will all have another trivia about the story.
Plus, if someone guesses how Shō will manage lead the story, you'll get extra trivia about some other character!  But be careful this time, you have to guess both questions or none of the two extras will come to light!
