let me analyse...
after you get the hikaru-1S, you will marvel at its beauty and you'll begin to feel the need to have a roy-1S.
you will think of roy-1S wherever you go and whatever you do and you'll even dream of it in your sleep.
you'll lose your appetite, feel lethargic and become aimless in life.
"the only way to cure this sickness is to get a roy-1S", you said to yourself.
and finally, you'll find yourself going to a toy shop and pick up one roy-1S........then life is back to normal again.
