Blue Lock: I Set My Sights on Becoming the World's Best, but Awakened a Conquest System

[Primarily Blue Lock + Original Protagonist + Everyone Has a One-Sided Crush on Him + Genius + Dating System] The System doesn't get much screen time, and the protagonist doesn't rely on it to get stronger. It's mainly there to show him people's affection levels, although sometimes a System update might make him lose consciousness... The protagonist is a native of this world. Itoshi Sae: Mizutani, team up with me and become the best in the world! Mizutani Tsubaki: The world's best striker? That's obviously going to be me. Itoshi Sae: ...But you're a midfielder. So what? He's a genius. Mizutani Tsubaki is an all-around genius who has never lost a match, from childhood to adulthood. After getting bored and giving up tennis, volleyball, badminton, and other sports, he tried soccer for two months at the age of thirteen. Then he played in a practice match against a powerful opponent and, as a midfielder, turned the tide of the game... only to lose 5–4. He then decided to become the world's best striker, and that's when he awakened... a dating System? And so his life changed completely as he set out on the path to becoming the world's number-one striker. [The author knows next to nothing about soccer. Everyone has a one-sided crush on the protagonist. After losing once from the start, it's smooth sailing all the way.]
