A Worry
A Trouble
noun
This is the noun version of worry, making it a worry, or a trouble.
The reading is the one you learned with the kanji. Nicely done, no need to have a worry about it.
悩み事の相談に乗るのは構わないんだけど、金欠なんだよね。外食したいなら、あんたの奢りだよ。
I don’t mind hearing your advice about my troubles, but I’m running out of money. If you want to eat out with me, it’s your treat.
