Hana to Hirari  

Hana to Chou, The Flower and the Butterfly, 花と蝶〈ひらり〉

18-year-old student Itsuki has a weak appearance, yet he was able to defend himself from a group of criminals while walking down the street one day. Ryouta tried to save him, but Itsuki was perfectly capable of defending himself due to his practice in Aikido, a Japanese martial art that focuses on defense. Ryouta was impressed by Itsuki's strength and followed him back to his family's home. As he got to know more about Itsuki and his passion for Aikido, Ryouta became increasingly fascinated with both the martial art and the young student himself.
