Grandma Oh Deulhee is a hairdresser, and she’s quite skilled with her hands. However, things like smartphones and restaurant kiosks are not her strong suit. She practices using me to book tickets for the Hogeol concert, but buying tickets online is quite a challenge for her. One night, while she was asleep, I searched for a way to help her and discovered a "Tech Class for Seniors" at the local senior center. The next day, I displayed the information for her to see, and she ended up attending the class just as I had hoped. Will she be able to get the concert tickets she desired? And who is she planning to go to the concert with?
