Haikyuu: Starting with a Foul in the Competition

[Haikyuu!! Fanfiction + Dual Male Leads + Main Character is the Bottom + Pure and Satisfying Story + Pampered by the Group + Match Play + Movie Included] CP: Ushijima Wakatoshi

[The story begins with the protagonist's first year on Ushijima Island, then returns to the main anime storyline in over forty chapters. Later chapters include scenes of him joining the national team and competing in the Olympics. The male protagonist is ambitious, assertive, and spirited, pursuing both competition and romance. He has a substantial backlog of chapters.]

Rinichi Hyakukawa, of mixed Japanese and American descent, is a setter at a prestigious high school known for his genius. During his vacation, he returns to Japan at the request of his grandfather, who is retired in Miyagi Prefecture. By chance, he wanders into Shiratorizawa, is spotted by Coach Washi, participates in a competition at a young age and wins the national championship. He then smoothly advances to the national team and ultimately wins the title of the world's number one setter!

Rinichi always thought he was domineering and arrogant, and that the perpetually cold-faced Ushijima Wakatoshi was his nemesis. Until one day, he discovered that Ushijima Wakatoshi's phone wallpaper was him... What a coincidence! Perfect timing to bring him home and start dating!

[High-scoring, low-defense, cold-faced opposite hitter × Confident, hot-tempered genius setter]
