You need to send a commemorative message to sign the contract.

After signing the contract, I was excited, but there was also a sense of pressure, and I don't know why this mentality appeared.

To be honest, I still don't know how the editor's guts for this book came about.

For this, I sincerely thank and admire the editor.

There are a lot of accidents in life, so I can't guarantee anything superfluous here.

Try to do your best to reach my limits, and that's the biggest guarantee I can do.
