[Crossover] My Dad Is Keigo Atobe

Jiayu Jibu is an ordinary high school student whose current goal is to build his own business empire someday. He never thought there was anything special about him, aside from managing several companies and having a particularly rich family. Oh, and one more thing: his dad is Keigo Atobe. It wasn't until he suddenly transmigrated to a different point in the timeline that he realized he might have underestimated just how extraordinary he was. * As someone who had once come close to becoming a professional tennis player, Atobe had been quietly preparing plenty of tennis training and paving the way for his son ever since Jiayu was born. Atobe watched with satisfaction as his son's tennis skills improved day by day. After Jiayu started middle school, he successfully joined the music club. The music club?!! After a heartfelt father-son conversation, Atobe finally accepted reality: Jiayu simply did not like tennis. Jiayu: Is making money not fun enough, or am I not making enough? Why play tennis? Watching the sons of Tezuka, Yukimura, Sanada, and others pick up their rackets to follow in their fathers' footsteps, Atobe forced a smile and ground his teeth. * After hearing this earth-shattering news, Atobe once sought out Oshitari to vent his frustration: Atobe: Tch, that kid is nothing like I was at his age. Oshitari: Don't be ridiculous. Jiayu is the spitting image of you back then. (Except for the beauty mark and the weird catchphrase, he thought to himself.) Atobe: But he doesn't even like tennis. Oshitari: Look on the bright side. At least Jiayu doesn't like basketball either. Atobe: Hm? What kind of unglamorous consolation is that? * When time turned and Jiayu's timeline ran parallel to that of 15-year-old Atobe, he changed his identity and joined in their youth. He seemed to finally understand a little of what his father felt. Jiayu: Hm? Tennis is actually pretty fun. * Extra Scene 1: The timeline got scrambled, and six-year-old Jiayu Atobe landed outside the gates of Rikkai High, back when his fathers' generation were in their final year of high school. Yukimura [stroking his chin]: This kid somehow looks familiar. Yanagi: The probability that he's related to Atobe is 93.62%. Jiayu, shrunk from a high schooler to an elementary school student: ...What's going on? Am I really not dreaming? At that moment, Atobe came from outside to challenge Rikkai: Hm? I'm looking for Sanada... Why are you guys all looking at me like that? Extra Scene 2: After being forced to spend some time as an elementary school student in another world, Jiayu finally couldn't hold back one day and confessed to his new friend: Conan, I'm actually a high school student. I only ended up here because of a twist of fate... Conan: ! Jiayu: I know it sounds unbelievable. I never expected to wake up one day and find myself shrunk down to a little kid, either. Conan: !! Jiayu: Sigh. It's so unglamorous to have the mind of a high schooler but have to go through elementary school all over again to hide my identity. Conan: !!! * Jiayu Atobe finally made it back to the timeline where he was 16. He thought he could return to the future, but instead time moved backward again, taking him to the world of his fathers' generation when they were in their final year of middle school. An invitation to the U-17 training camp arrived in his hands. [Have you heard? They're starting to recruit middle schoolers this year.] P.S. There are secret identities and identity reveals.
