菊地真さん、そしてアイドルマスター16周年おめでとうございます！
16歳まこずーっと大好き！無印リメイクしてくれ…
2枚目は担当プロデューサーの思い出コメントぽいもの、
3枚目以降は後ろにちりばめた写真たちです。思い出がいっぱい。

From the commentary image (91502470_p1):

真は休日だったのだがメールで呼び出され、二人で夕焼の海を見ながら話をした。
また来よう、と約束。

Congrats to Kikuchi Makoto-san on Idolmaster's 16th anniversary!
I love 16 year old Makoto! Give me a remake of the original...
The second image are something like the comments on memories from the producer;
the third image and afterwards are the inset photographs. There are lots of memories.

From the commentary image (91502470_p1):

Even though it was her day off, she messaged me asking to meet up and the two of us talked as we watched the sea at sunset.
We promised we'd come back here.
