Bu Er Huanyan overheard her parents talking and suspected she wasn't their biological child, and that her birth father might be a friend of theirs.
She didn't want her father to find out she knew the truth and be heartbroken, so she secretly tracked down the friends he'd played tennis with as a teenager.
Seigaku, Hyotei, Rikkai Dai, Shitenhoji...
She didn't let a single suspect slip by.
Just as she'd gathered the evidence and was about to get a paternity test for all of them at once, a car accident sent her fourteen years into the past.

When she opened her eyes again, she found that the boy who had hit her was Atobe Keigo.
After looking at the student ID and photos on Huanyan's phone, Atobe tapped the beauty mark at the corner of his eye. "So your dad is Fuji Syusuke, your uncle is Yukimura, your coach is Tezuka, and your godfather is Echizen Ryoga."
Huanyan nodded.
Atobe: "What about me?"
Huanyan: "We're not close."
"..." Atobe: "Who do you suspect is your birth father?"
"I don't know." Huanyan added, "Except for you, all the uncles from the school tennis teams are especially nice to me in the future!"
