"Hmm." Tianxin nodded, not denying it.
"But I seem to remember you said just last week that your period was coming soon?" Chen Yiran raised an eyebrow slightly, looking at Tianxin with apparent confusion.
"I..." Tianxin paused, forgetting to chew the sandwich in her mouth.
She looked down, counting on her fingers, then looked up at Chen Yiran with teary eyes, "It... It seems like I'm already four days late... what should I do?"
"Weren't you always regular before?" Chen Yiran asked, slightly frowning.
"Yeah, I've never been irregular before!" she nodded vigorously in agreement.
"Is it possible... that you're pregnant?" Chen Yiran looked at Tianxin and offhandedly asked.
"No way!!" Tianxin froze in shock. She crawled over to Chen Yiran, clutching his sleeve, "Are you serious?? I'm only in my first year!! If I am, my parents will kill me!!"
"I was just saying." Chen Yiran couldn't help but laugh, patting her head, "It could just be late."
