HP correction.

HP has been slightly revised.

I customized the online shop to make it easier to use and browse (lol).

It's at a level that first-time viewers won't understand though ^^;

Before I knew it, it's been three years since I started this website.

Everything on the internet is fast: information, changes, responses, etc.

Therefore, if you leave it for even a little while, it will become stale and lose its freshness.
