Three Encounters, Falling Thrice in Deep Love (10)

After walking a full circle around A High School, Qin Zhi'ai checked the time on her phone. Discovering it was almost noon, when students would be rushing out of school, she started to walk toward the school gates to avoid being jostled by the kids. 

As she reached the gates, she was stopped by a security guard she knew, who said, "I was about to drop you a message to notify you that there's a letter for you. It's such a coincidence that you're here today."

She'd only replied to Mr. S's letter a few days ago, so she was stunned for a few seconds, as typically she'd receive replies two to four weeks after sending her letters. 

Qin Zhi'ai followed the guard to the security room and, upon receiving the letter, she thanked him and chatted idly for a while. Only when she heard the school bell ring did she say her goodbyes and leave the school.
