Translator notes forn English lyrics:

[1] Possibly a variation of uttari, meaning comfortably, or easily.
[2] Beta is the sounds of a flat surface coming into contact with something else repeatedly.
[3] Can also be translated as "Go out with someone who's more sensitive; me!"
[4] No matter what I tried, I could not find a translation for mido. The closest thing was midori, meaning green.
[5] Literally, "you're at the peak of life now."
[6] Yet another sound effect I wasn't able to find a translation for.
[7] Awa awa is the sound effect of bubbles popping.
[8] An asterisk is this symbol: *.
partially translated from the fansub below; rest is self-translated
