The Moon on a Rainy Night, Volume 4 (The Moon on a Rainy Night #13-16)

One day while having lunch in the Literature Club room, Kanon learns about a surprising club tradition from Miura-sensei. Every year, club members spend summer break writing something for the school's literature contest. Miura-sensei surprises Kanon even further by complimenting her writing and encouraging her to enter something for that year's contest. Though Kanon is initially reluctant, she later finds herself mulling over everything that's happened since she lost her hearing and met Saki. Could there be a story in there somewhere? Meanwhile, Saki gets roped into playing piano for the upcoming choir contest. Now she just has to find the perfect song... and hope her classmates can accept Kanon in the choir.
