The first time Aomine gave Momoi a piggyback ride happened at the night they ate ice cream with Kise for the first time. After that bastard pushed Momoi to the ground, Aomine had more reasons than one to catch him and beat the shit out of him. Unfortunately, Murasakibara had all the fun, because of some ruined ice cream.
By the time they returned, they found the remaining members of their group in the park nearby to the convenient store with Kuroko bandaging Momoi's knee.
"Is it better now, Momoi-san?" Kuroko asked with worry in his voice, looking up to the girl.
"Yes, thank you, Tetsu-kun!" Momoi answered with a huge blush on her face. She tried to stand up, but winced in pain. "Ouch!"
"In my opinion you rather are taken home on someone's back or in arms," Midorima said, looking aside. "Not that I am really interested or anything..."
"Here, Sacchin," Atsushi said, giving her one of his precious maiubous from his bag. "Maiubou is the best medicine ever."
Kise only stood there in awe, watching as all of them taking care of Momoi in their own ways. He knew that he should do something too - he only had no idea what. He saw as Aomine passed him, touching Momoi's shoulder gently.
"Can we go?" He asked on a voice Kise never would have thought he would use. Ever.
Momoi only nodded, smiling happily. As they walked away, Kise see how her smile widened on her face from ear to ear.
