Kodomo no Omocha (TV), Chihayafuru Recommendations
If you are a fan of Taichi and Chihaya's relationship then I recommend this anime to you. Although Kodocha is not sports anime, Taichi and Chihaya's relationship reminds me of Sana and Akito.
Taichi reminds me so much of Akito, on how Akito is always there for Sana and although he love her so much he couldn't get himself to tell her about it.
Chihaya reminds me of Sana she is very dense when it comes to love. She never noticed Akito's feeling even though they are almost always together for each other.
The way that both of them make each other strong and bring each other's confidence
