If he wanted to be totally honest, he sometimes felt uncomfortable when he saw how comfortable Satsuki behaved around his Touou teammates, especially Sakurai. They were in the same class, so Aomine had to witness their every little fluffy encounter.
"Ryo-kun is so cute!" Momoi said once as they were walking home. On that day, Momoi overslept, because she had organized data until midnight on the previous day and she forgot her bento at home. Sakurai - just like the little gentleman he was, shared his with her. "And his drawings are pretty too!"
"I never would have thought that you were that adulterous, Satsuki," Aomine said, his arms being enlaced behind his head. Momoi sent him a questioning look. "First Tetsu, now Ryo... What is so special about them, I wonder."
Momoi's gaze turned from questioning to angry within seconds. She stomped her foot in anger and ran forward without a word. Aomine had a feeling that she would calm down during the night - at least, he really hoped so.
It turned out that he was wrong. When they met next morning, Satsuki paid no attention to him, only started walking towards the school without even giving him an angry look, just to acknowledge him being there, walking behind her.
As soon as they stepped into the classroom, Momoi walked up to Sakurai's desk, smiling down at him with her kindest smile.
"Good morning, Ryo-kun!" She greeted him, which made the shy boy blush.
"S-satsuki-san, good morning!" He replied, his blush spreading on his face.
Aomine could not believe it. Why does Satsuki call Ryo on his first name when he became 'Aomine-kun' on their first day in middle school? But what was more important, why did Satsuki let Ryo call her on her first name?! Aomine bit into his lip to hold back a growl.
He looked at them again and saw as Satsuki gave a wrapped up bento box to Ryo, who took it with a slightly trembling body. Aomine could not take it anymore. He stood up and walked to the two, maneuvering Satsuki behind himself.
"If you do not want to go to the infirmary, you better not eat that, Ryo," he warned the boy and the shaking became more visible - but what he did not except was when Ryo's expression suddenly became determined.
"O-of course I will! Satsuki-san did this bento with all her heart and I really appreciate it!"
Aomine stood there dumbfounded. He did not understand why the other wanted to sacrifice himself, but when he saw Satsuki hugging the brunette to herself with happy tears in her eyes, he started to think about what if he was the one who lacked some basic knowledge about women.
