Note addition:
[13] The Japanese believe that when you sneeze, someone else is talking about you.

Translator notes:
[1] Literally, “it will hurt to the point of being kind.”
[2] There are two words for love in Japanese. Koi is a long-term, everlasting, serious love; ai is all other kinds. Koi is used first, than ai.
[3] This is a spoof of a proverb; literally it means “Dig your own grave while loving in high spirits!” The proverb actually is “don’t live in high spirits just to dig your own grave.”
[4] Usually, let’s go is ikou, but iko’s meaning, orphan, didn’t quite fit here.
[5] Literally, “because love is a giant step!”
[6] Literally, “love a woman, honorable person!!”
[7] A proverb again. Literally, “Planted peach and chestnut seeds take three years to bear fruit, plums take eight.”
[8] The furigana here goes haohao, but no matter where I looked that made no sense, so I used the original meaning of the kanji.
[9] Yet another proverb; literally “Good fortune and happiness will come to the home of those who smile.”
[10] Another parody of a proverb again. The proverb is “Many a little makes a lot.”
[11] Still another proverb parody here. The proverb reads “what one likes, one will do well.”
[12] Yet another proverb parody. The original is “time is money.” Also, zen is a counter for chopsticks or bowls of rice.
