For those who think she hated Sunrise in the beginning, I made a translation mistake...

It should be:
“At first there were no plans to make Sunset. I had prepared a completely separate ballad, but when I started working on Sunrise, I unexpectedly started ‘fighting’ with the ballad. Midway I thought, “I hate this, I can’t sing it”, but, in the end, a song that I loved was completed*. I started thinking about how I wanted to create that child’s other self. Originally, Sunrise was very energetic but because the melody was very pretty, I felt I could try to turn it into a ballad. That became the plan (laugh).”

She actually disliked the ballad she had made before Sunrise. But as she made Sunrise, she got the idea to make Sunset. Resulting in a ballad that she did like.
