descovery!!

I bought a free pass in USJ when I was second grade in high-school.
It was very expensive for me to buy it but I could go there many times and whenever I want.

I like USJ very much and I would often go there with my friends after school or weekend.
One day,I realized something extraordinary happened.
When I go to USJ,I always have a stomachache,especially,near bellybutton....
I don't know why I have a stomachache.
My friends doesn't believe my experience and they laugh!
I want a doctor to see my abnormal change but After I left USJ, this strange symptom disappears quickly.
Recently, I have many opportunities to go to USJ with them because almost my friends bought free passes.


I think that finding some solutions has much more times but I want to find them immediately!

Now,I don't want to go there because I am afraid of experiencing this situation again.
However,I want to see Christmas tree in USJ!
