[Prince of Tennis] Host, Please Choose

[Important] This is a Mary Sue story I wrote when I was young. Years later, I've dug it up and rewritten the whole thing from scratch. The main goal is to finish what I started. I can't be bothered to delete the comments; they're relics from ages ago, so just ignore them. This is absolutely a piece of my cringey past, and absolutely a Mary Sue story. Don't come after the heroine for being too perfect or for her name and intelligence. I'm writing a Mary Sue, and that's that! (shouting) After an accident, Bing's mind somehow fused the memories of two people from reality and an animated series, and she also inexplicably got a System. “Hello, Host. System No. 305 is at your service.” She thought it would be a golden finger that could help her conquer the business world, but before long she realized... something about this didn't seem right?! “Please select your main romance route, Host.” “Please select your romance target, Host.” “Please select your multiplayer mode, Host.” Bing slowly typed a question mark. This System... could she just not have it?! System No. 305, an emotionless quest machine: “Daily quest: Please hold hands with Yukimura Seiichi.” Bing took a deep breath, about to unleash a stream of curses in her mind. System: “Host, think of the points shop.” Bing: ... Bing: Endure. (smiling through the pain) * The first time Yukimura Seiichi saw Bing outside the hospital was when she had a sudden fit of kindness and led a lost seaweed-haired junior to a tennis club. After a friendly exchange between the two fellow patients, they were about to go their separate ways. Then he saw his fellow patient pause mid-turn, as if she'd heard something. Her expressionless face grew even stiffer, and then she turned back toward him. “Yukimura, could I borrow your hand for a moment?” Yukimura Seiichi was confused, but still held out his hand with a smile. “What's wrong?” “Thank you.” His fellow patient quickly shook his hand, sincerely said goodbye, then turned and ran off. Yukimura Seiichi was left with a question mark slowly appearing above his head. “...Huh?” 1. No. 305 is taken from Yukimura's birthday, March 5. 2. This is a very traditional, old-school Mary Sue setup with an old-fashioned System. If you're looking for something new or silly, feel free to leave. 3. She won't deceive anyone's feelings to complete romance quests. Enjoy the sweet romance; there won't be angst. 4. The character names are listed in the cast page. I came up with them when I was young and clueless over a decade ago. This really is my very first story, the one that inspired me to write. I accept that it's cringey, but I don't want to change it and won't. Feel free to poke fun, but don't argue that it's too Mary Sue and makes your eyes bleed or that you can't stand it. I've put the warning here, so if Mary Sue stories are a dealbreaker for you, don't read it. 5. This story runs on love and inspiration, so updates are whenever I can manage. I'm busy with real life, but I can promise I won't abandon it. Little angels are welcome to remind me to update. Don't try to force me to churn out words like a robot unless you're paying me. That's all. If none of the warnings are dealbreakers for you, then, since I'm terrible at blurbs, please read the story. Theme: Today, I, Mary Sue Bing, will use a romance System to reach the top of the business world
