Xiao Chengjun almost dropped his eyeballs when he saw their act, ready to acknowledge family relations so readily.

"Ahem... Ahem..." He coughed twice in a row before suggesting, "Don't you think that just relying on your eyes to judge might be a little hasty? If you want to determine if you're twins, shouldn't you start with a DNA test first?"

An excited Qin Yutong cooled down a bit and nodded firmly. "Right, we should prove it with science!"

"DNA? Sounds quite grand!" Lin Haoran, who'd often seen DNA testing on TV, was very interested. He found it fun that he could do a test too, this time. "When should we take the test? Now?

Qin Yutong looked helplessly at the man who might be her brother. "Maybe we really need to do the DNA test- why do I feel like I shouldn't have an idiot brother?"
