Lu Xun, Who am I?

When Lu Xun woke up in the morning, the sky has already turned bright.

He looked at his surroundings and then, his gaze fell on the pajama on his body. A frown appeared on his face as he tried to figure out just how did he return home and changed the clothes on his body.

Lu Xun seemed to remember that he had accompanied Song Yi for a drink as they discussed some business matter.

Initially, Lu Xun had no intention to drink too much. After all, he still remembered his father-in-law's reminder not to drink too much.

However, Song Yi had diverted the topic of their conversation to Song Xing Xing. Song Yi was a little drunk as he mentioned a few things about his cousin. In the end, he had mentioned a few matters that made him unhappy.

Lu Xun wanted to suppress his unhappiness and drink a little bit.

In the end, what happened?
