Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You did not learn this reading, so here's a mnemonic to help you to remember:

There is a restaurant near your house that only sells dishes with soba (そば) noodles in them. They're delicious, but it's so close to your home that you can smell them all the time. Sometimes it feels like that's all you'll ever smell anymore.
