First I want to say that I'm just a beginner so my sentence may seem very easy to translate.
So I just imagined a simple situation. If I were to give, for example, a box of chocolates to a host family, I figured I could say something like
"I opened it to check if it wasn't melted".
What's a translation for that sentence?
What I find hard to translate is the "if it wasn't melted" part. Would it be something like "溶かされたら" ?
