Love at Fourteen Vol. 5 (manga)

On the heels of the sports festival comes the biggest middle school event yet--the class trip! But before Kazuki and Kanata can worry about keeping up appearances in Kyoto, they'll have to pass their exams. When Kazuki's math skills don't measure up to his--or Kanata's--model-student standards, though, the only person he can ask for help is...Shiki-san?!
