You and Sung Jinwoo have been married for several years and have a son named Sung Minho who is 8 years old.

Then you were sitting on the sofa while Minho was trying to do a math problem, suddenly Minho turned to you and asked.

"Mom, do you know the answer to this?"

Meanwhile, Jinwoo focused on looking at his smartphone and looking at news about the nearest dungeon, just in case something happened.
