No-one knows that's my family

In class there was a true mess. Almost everybody was chatting. When Kei and Alex entered the classroom, Alex had some ideas about what they were talking about, while Kei was simply curious. He was not on social media, he simply had MessageAp (an app to write messages). He then asked Alex "What's up with everybody?""Didn't you see it on TV?""You know I don't watch the tg""Yeah, right. Anyway, didn't you hear? Kishimoto senpai (the girl one) won the ice-skating tournament, but not the Japanese one, I mean she won against all the other girls of the world, and her little brother qualified for the Olympics. Isn't that great, not that if I would try I wouldn't be able to do the same""Yeah, sure""You don't believe me""You are the worst when it comes to PE""Th-That's not true! I-I'm simply not doing my best""Wasn't doing your best part of your goals?""Wwweell" As you might guess, Alex was panicking, infact he was really doing his best at PE, but he would have never admitted to be so bad. "Anyway, I'll challeng Kishimoto senpai (the male one, to challeng the girl one would be disrespectful)""Isn't that quite a chauvinist way to see it? Are you saying this because she scares you more?""No!""Well, I agree that he is a brainless gorilla idiot all-muscles""Did he do something to you?""Not at all!""I didn't say anything of that though. You know that he is a sport star? If anybody of that world would know what you just said, you would find yourself in trouble. Not to mention if his family found out""I don't think they would do anything" Kei said so with a strange expression, but Alex didn't notice that. "Are you kidding? What would you do if a stranger would criticise a member of your family? And his family has even unthinkable power""Y-Yeah, r-right. Wait! You are in a similar situation. Wouldn't they take it as an insult if a duffer in PE would challeng a world champion?""Hey, now you are the one insulting""Just telling the truth". They were almost the only ones talking that way about that, all the other schoolmates were saying words of admiration, although everybody who personally knew their senpai, Kenji Kishimoto, thought he was an idiot, they were just being careful because of his family. There was just one girl openly bad talking about him, or, more likely, saying her true opinion. She was called Shizuku Aikawa. She had long blonde hair and brilliant pink eyes. She was quite popular because she came from an important family (the Aikawa team, a famous international bank), but was always being compared with Kishimoto senpai, being belittled. There were student saying that next year they will have to be satisfied with 'simply' her, because Kishimoto-san is at her third year. Students of other schools were jelous of them though. Anyway it seemed that Aikawa had it with both the senpais and everybody was saying she was gelous, but she always said that that was not the reason. She reminded to Kei of his childhood friend. And maybe she was, but he thought it was impossible, she would have recognised him.
