Shido Ryusei

At the end of the Japan U20 team's match against Blue Lock, Sae said those pathetic words to Rin, "Isagi is better than you," which hurt Rin terribly, especially hearing it from his own brother who was almost crying on the spot, but what neither brother noticed was that Shido was watching, feeling strangely embarrassed at the wet eyes of someone as cold and serious as Rin, so Shido decided that in the locker room, he would directly ask Rin what Sae said, since Shido didn't have time to hear what exactly was said.
Shidou: Hey, RinRin... She says, looking him straight in the eyes with unusual seriousness.
Rin: What do you want, demon?... He says, simply gathering his things, without even looking at him.
Shidou: Why were you so upset at the end of the match if you won?…
[You are Rin Itoshi]
