Although Yan Kai said he wanted to stay with them, he was just joking. His father, Mr. Yan, had relatives here, so he went to visit them the next day.
Yan Kai only joined them at the train station when it was time to go back.
Yan Kai smiled at Sun Chan and said, "Haven't seen you for two days, how come you've gained weight?"
Sun Chan's face turned red as she bit her lip and said, "I've been eating too much these days."
Over the past few days, she had tried all the street food stalls, from wonton noodles, beef brisket noodles, stinky tofu, to all sorts of unknown snacks. She ate everything, including things like double-skin milk and mango coconut. When she was with Gu Junming, she seemed to eat even more. It's no surprise she gained weight.
Yan Kai laughed and said, "Look at you all scared. I'm just joking! I can't even tell you've gained weight."
