Finally, this is the version with Nishida.

By saying how I really feel, people gives me a lot of pressure, some is from others, some developed by myself. Although life is tough, but I still try my best to smile to everyone. In deep heart, I create a character who absorbed all these negative feelings, and he helps me a lot on managing myself, so he is a very important original character for me. Even he will never have "extra emotion" from now on.
[If you noticed carefully, Nishida didn't ever laugh or happy face before, although he has smile sometimes, but is quite cold because of me]
