While directly translated as "The Moon is Beautiful", the phrase "Tsuki ga Kirei Desu ne." (月が綺麗ですね。, lit. "The Moon is Beautiful, Isn't it?") is a famous Japanese way to say "I love you". The phrase was translated by Meiji-era novelist and teacher Natsume Sōseki since he believed that two people in love do not need direct words to convey their feelings
Учитывая любовь ГГ к классике, название очень подходящее.
