There’s a box in Dongwoo’s room. One day, Dongwoo’s mom said that she was going to throw it out but Dongwoo refused. Dongwoo’s mom asked why and he said that it has the debt that he has to pay for his whole life. Inside, there’s the receipts of what Dongwoo’s parents have bought for him and a paper written with every little thing that his parents have done for him. Dongwoo’s mom cried after that.
