To understand the scene from the previous chapter, let's go back to one week before.
It was Saturday evening, the first week of October. Autumn's wind is cold, Zhen Guo feels lucky he wore a thick sweater and padded jacket. His wife chose his clothes for this evening.
It was rare for his friend inviting them to drink. If this was 15 or 10 years ago, it was not a surprise. They went to the bars and lounge almost every week when they were young. But after they have their own family, it was not an option anymore. Only on a few occasions they will go out together again like this.
And it's even rarer for his friend to invite them with just a short text message.
[Are you free tonight? Let's get some drinks.]
