No one told me I had to make something that would sell, but I personally want everyone to like my music.

The Japanese version comes with a translation, but that's different from the lyrics, so people could look things up and find a translation of their own if they're interested.

I bought an espresso maker and coffee maker and make them myself every day.

Since I was doing all of it myself, I had to decide where I wanted to go with the songs, how to proceed with the chords, if the sound was alright, and all that detail on my own.

Wish I could prove I love you, but does that mean I have to walk on water?

The thing is, in English I'm able to write the lyrics as I'm making the song, once I'm done with the melody.

In Japan, people don't really sing about sexual content.
