Ryosuke searched for more ingredients after Yamazaki accidentally ate all of the kimchi takikomi gohan. The only remaining item was a pack of beansprouts which he does not like. He found frozen udon in the freezer and prepared to cook zaru udon. A drunk Okochi then came to the office and instructed him to make a cold udon with mayo-mustard combination instead. Thinking the udon itself was not enough, Okochi took out the beansprouts from the fridge and told Ryosuke not to underestimate the beansprouts. She then proceeded to make a spicy beansprouts side dish. (Source: Written by MyDramaList)
