In second grade, he met someone.
That person can reach a tiebreaker with Yukimura, that person will reject anything that has nothing to do with tennis without hesitation, that person is really good at tennis.
On the second day of school, he met someone.
That person is a sports student, that person's grades are a mess, and the most frightening thing is, that person is actually a girl?
Every day from now on, he meets someone.
That person is a strong player, that person has 0 emotional intelligence, that person has nothing but tennis, that person will pester others to play ball every day, that person will eat all the time, that person can pronounce clearly with a mouth full of food, that person will unconsciously be evil, that person is very strange, yes, that person is the strangest person he has ever met, and he is also the person he admires the most.
It wasn't until much later that he discovered that he knew that person so well without him knowing it. Unbeknownst to him, he actually fell in love with that person. Maybe those other things are not reasons. There is only one reason for him to like her, and that person is Echizen Ryuichi. There is only one reason.
With just this thought, flowers bloom everywhere.
