I Want to Become the God of Tennis's Man

Everyone in the country's tennis clubs knew that Rikkaidai, known as the King, had its own cheering squad. Its greatest achievement: defeating Hyotei, a club with two hundred members. Everyone in the Rikkaidai tennis club also knew their beloved captain had a childhood friend he held dear. And no, it wasn't the vice-captain, who glared at them during practice every day. It was the lively and adorable music club president, who bounced around and cheered them on with drums and gongs every day. One day, while hospitalized, Fujiwara Shuya found a lost System. It told him that if he bonded with it and completed its missions, he could have a healthy body. Fujiwara Shuya gladly signed himself up. System: What's our goal? Little Shuya: To become the man who becomes the God of Tennis! Years later, the Rikkaidai captain, now a Grand Slam champion, smiled softly. "Didn't you say you wanted to be mine?" Snippet One: Fujiwara Shuya liked the older boy next door. He was the kind of boy who cheered him on at every match. Once, Yukimura won a match with a clean sweep, but people started a rumor that he'd won through unfair means. Fujiwara Shuya raised an eyebrow, put his hands on his hips, and let them have it. The rumor-monger covered his head and begged for mercy. "I've realized you're really particular about this sort of thing." Little Shuya: Nobody gets to bully my Seichi big brother! Snippet Two: Fujiwara Shuya liked the older boy next door. He wanted to confess to him. He shyly went to the System and asked, "Do you think he and I..." System: The world would be better off with two fewer menaces. A slice-of-life story. A music genius who lets familiar faces in and keeps strangers out & childhood friends to lovers Theme: Winter passes, and new grass grows
