Xinan unlocked her phone again, found the chat with Tan Bo on WeChat, and started typing, "Brother Tan Bo, are you free right now? I want to ask you about something."
Tan Bo was Cheng Yi's best friend, and there were some things he might know the reason for.
A few seconds later, Tan Bo replied, "I'm free, what is it? Go ahead."
"It's about a few days before I confessed to Cheng Yi during college, was he acting a bit off, emotionally?"
"Why are you suddenly bringing this up?"
Xinan sent him an emoticon, then said, "Just asking casually. If you don't remember, never mind."
At that moment, Tan Bo was drinking in a bar, surrounded by a noisy crowd, so he simply found a relatively quieter spot to reply to Xinan's message.
He lit a cigarette and began to recall the monotonous and dull days of college.
