閉じない目 (Tojinai Me)

Background
"Tojinai Me" is an original galaco song. The singer laments about losing sleep over the guilt that crushes them. They can't sleep until they've apologized, and have been forgiven. But to do it, they have to say "I'm sorry". When the singer finally does, they feel amazing relief, as if a humongous weight has been lifted from their shoulders.
