Tang Su's phone call was from her parents, who had been trying to reach her but couldn't get through. As it was starting to get dark, if they couldn't reach her on her cell phone, they were planning to contact Lu Han.
Finally, they got through.
Knowing that Tang Su didn't answer the phone because she had lost it, and not because something had happened, Tang Shengyi and Su Ruoan were relieved.
"Did you get your vaccine today?" Su Ruoan's main reason for calling earlier was to remind her of this, afraid that she would forget.
"I did."
"That's good then. Alright, I won't disturb your time alone with Lu Han anymore. I've booked the tickets to Beijing for next Friday. Your dad and I have also adjusted our annual leave, and your grandmother and uncle will arrive on Friday night."
"Okay, got it."
It was only Monday today, and next Friday was still a whole ten days away.
