Four college classmates came to Shanghai to play. I accompanied them for 6 days and spent 56,000. When they left, all I got was a thank you. Seven days later, I received a package.

The moment I opened it, my hands trembled. During those 6 days, I took annual leave to accompany them the whole time. I booked a hotel by the Bund with a river view, arranged local cuisine, Japanese food, and seafood banquets for every meal, took them to Disneyland during the day, climbed the Oriental Pearl at night, and went to bars and enjoyed the night view, making sure not to let these brothers who slept in bunk beds feel neglected. They kept saying 'what a waste of money,' but they were not polite at all, casually handing me the bill when buying souvenirs and saying, 'I'll deduct it from my living expenses when I go back.' I just smiled and waved my hand, saying, 'Are you going to settle this with me?'
