Different treatment

The next day, at school, Kei entered the classroom with Alex as usual. They were going to their seats ready to talk to Daisuke. And then they noticed. A girl, long blonde hair, was sitting with a borrowed chair, right in front of him. Yeah, exactly, that was Aikawa. Kei narrowed his eyes. What was she doing there? That was incredibly unusual. Then he looked at Daisuke. He was lost too. 'Just what...?' is what they were both thinking. Now, want a small flashback? Whatever your answer, I'll just do it. Early in the morning, Daisuke went to his seat in the classroom and started gaming with his phone as he usually did in class waiting for his friends. Then, as the class started to be filled with students, Aikawa came. She asked a girl with the desk near Daisuke's to lend her the chair 'till the arrival of the teacher and crossed her arms in front of him. "So, since when do you know Kei?". Yes, her goal was an interrogatory. Now, please don't take her as a yandere psychopath like some other girl, because she is more like an overprotective friend (without extreme obsession). "Why?" asked Daisuke, meanwhile wondering 'She used his first name?'. "Oh, well, you know, normal curiosity?". Obviously, the direction Daisuke's thoughts had taken was 'What's gotten into her? She would've just ignored us until yesterday'. Then the door of the classroom opened again. And here we are, our situation! Yep, the situation had just gotten more chaotic. Kei and Alex sitted, both looking at Daisuke and Aikawa as if they were looking at aliens. Kei then connected with what happened the day before, differently from Alex, who was in his 'dumb mode'. Naturally, Kei understood that they were interacting because of that, but he wasn't sure about the exact reason she talked to Daisuke first thing in the morning. Alex then shrugged his shoulders thinking she just wanted something for school. The reason he didn't care? The girl who had no relationships and the boy who talked too much were coming in. Yeah, exactly, since when he discovered Kei's secrets and started to 'pay more attention' to his surroundings, he never stopped observing those poor classmates. You know why? Because those two had started interacting and they reminded him of some romance anime he heard about. Oh, and he kept using the excuse of 'having to keep an eye on everybody surrounding them'. In short, he is enjoying a real life drama, or, as I prefer to say, he is invading their privacy. He then said "Silent-girl and chatty-chatty are talking to each other again! Must be since yesterday when I was distracted". Having said that aloud, Daisuke and Aikawa interrupted their conversation, noticing only now Kei and Alex (they were both weirdly concentrated), and Alex received surprised (to say it kindly) gazes from the three of them. "What are you talking about?" said Kei. Then Alex tried to explain what he had been doing (the nicknames are because he still didn't remember their names), although Kei tapped his mouth with a hand (Alex almost talked about the emails in front of the two people Kei absolutely didn't want to know about it). For Daisuke and Aikawa, Kei's reaction was extremely suspicious. Anyway, Aikawa was still evaluating Kei's friends, and her opinion of Alex was about to reach absolute zero. Daisuke, instead, was receiving a passing grade. Aikawa, then, said hello to Kei (only to him) with a huge smile on her face. Two minutes until the start of the lesson (more or less, I mean, the teacher could be late). The door opened again. A short, long moment. Daisuke's gaze locked with the one of the person at the door. His eyes opening. Tanaka headed directly towards him, at the last moment turned and took Aikawa's chair while she was seated. Aikawa, who grabbed the desk on time, almost screamed 'What's her problem!' when Kei whispered in her ear "She is crazy, luckily there's already a sacrifice". Aikawa stopped while turning completely red and almost falling for another reason. Then, when her friends arrived, she was kinda forced to go with them. In the end, her interrogatory of Daisuke brought to nothing except a crazy girl considering her an enemy in love (absolutely mistaking, but you know, love makes you blind).
