Revised blurb.
A story about saving his childhood sweetheart, helping the tennis-playing Fuji regain confidence after giving up the sport, rekindle his love for tennis, and make their way to the nationals and then the world stage side by side.
Since kindergarten, Toyotomi Mitsuya had treated Fuji, the boy in the class next door, like a little brother and looked out for him. After they won a doubles championship together in elementary school, Fuji confessed to him.
Mitsuya was conservative, and his childhood sweetheart was such a coward that he packed up and transferred from Tokyo to Kansai overnight. He became the new captain of Makinosato, a once-glorious powerhouse now in decline, and the following year carried on the glory of champions brought by his senior Byodoin.
After the story begins, during the National Tournament, the protagonist happens to spot in one of the finalist teams the person he has always loved, whose every feature, from his hair to his sneakers, perfectly matches his taste. He is instantly smitten all over again.
When they reunite at U-17, Fuji is lost after losing his guiding star.
The protagonist is overflowing with confidence, but after his childhood friend, who holds a grudge, ignores him several times, he finally realizes the danger of having been apart for three years.
So he decisively tears up an invitation from a professional team, packs his bags, and transfers schools to win his sweetheart back. He brazenly inserts himself into the 36 and says with an innocent look:
"I'm not here to break you up. I'm here to join you."
A forceful, tsundere, jealous childhood-friend top with the greatest talent VS a gentle, scheming genius beauty bottom
A feel-good story with no angst for the protagonist. He and Fuji, who is two months older, will grow side by side. Fuji will become an all-around player and reach the top of the world stage.
Additional setting notes and potential spoilers:
1. During middle school, Fuji has someone he likes and admires, but it never reaches the point of romantic interest, since the protagonist is his first love;
2. The protagonist's career takes up more of the early story, with the romance introduced later. Fuji will be a little more assertive at times, since Gugu likes him best when he's an unpredictable genius who handles every situation with ease. So in their interactions, he may take the lead more often.
3. The protagonist will poach players from other schools.
4. Makinosato is the best, so don't ask whether Seigaku, Rikkai, or Hyotei will win. If you care about the match results, this probably isn't the story for you.
5. Original characters in fanfiction may inevitably be out of character. I'm open to feedback and criticism if the writing isn't good, but please don't make it personal. Thank you.
Theme: Losing your way as you grow up is still an invaluable experience
