パン祭りの告知に気づいてしまった

A few days ago, I bought bread.
When I came home, I saw a notice which was written on the bread bag.
It was about a certain festival.
The festival takes place every spring in Japan.
Entering this festival is to buy a lot of bread from a certain company.
I had taken part in it last year for the first time.
Because I decided to take part in the festival, I thought I sure want to achieve my goal.
While I had entered it, I had eaten much bread day after day and I had been wondering I would be an illness.
When I completed my goal, I felt I had never wanted to do it again.
But now I feel like I already participate a little.
It's super dangerous.
I have absolutely to stop me.
But I've known I will end up entering the festival again.
