「I was always stubborn and refused to deviate from the things I've decided,
making enemies wherever I went and was unable to be true to myself.
Whenever things weren't going well,
even if Tsunku-san wasn't nearby or anything,
he would hear about it somehow.
And then he'll contact me to talk to me about it.
It's because of Tsunku-san that slowly, my heart began to open to others.
Even if it were something I couldn't discuss with anyone else,
I was able to talk to Tsunku-san about it」
