"Brother didn't bring any food! Sister, help mom deliver a lunch!" Mutu's mother shouted from the kitchen.
"I know!" The answer was Bokuto Yui, Bokuto Kotaro's once genius sister.
"I know about training all day long, and I don't remember anything else." Yui ran to the training ground, huddled on the steps at the door, looking at the high-spirited attacker inside, "Training."
"Oh, isn't this the sister of Mutu's family? Is she here to feed your owl again?" A boy with messy black hair suddenly poked his head out of the venue, "Sighing blindly is not a good habit~"
The light from the training ground projects outward, pouring down from the boys' heads, like the rising sun of youth pouring onto the girl's face.
Raising his head, Yui asked: "Who are you?"
Purpose: Kuroo-senpai finally became a volleyball promotion expert, dedicated to making more people fall in love with volleyball. In his more publicized high school years, he must have hoped that volleyball could help more people become better versions of themselves. I hope Yui can also find the meaning of her life.
