ある日、ミト（田牧そら）の父親・聡（斉藤陽一郎）が家に訪ねてくる。一緒にお土産のケーキを頬張るミトだが、何だか浮かない顔。一方、チサト（手島実優）はアイドル深山龍太郎（寺坂頼我）の撮影に挑んでいた。撮影は順調だがチサトもまた何か複雑な表情を滲ませるのであった。２人の胸の内に秘めた感情が、シャッター音と共に少しずつ流れ出してゆく。
One day, Mito's (Sora Tamaki) father, Satoshi (Yoichiro Saito), comes to visit her home. Mito chews a souvenir cake together, but his face doesn't float. On the other hand, Chisato (Miyu Teshima) was trying to shoot his idol Ryutaro Miyama (Yoriga Terasaka). The shooting was going well, but Chisato also exuded some complicated expressions. The emotions hidden in the hearts of the two of them gradually flow out with the sound of the shutter.
