I think I've made a new discovery: Yi Xiaochuan and Da Chuan's dad, Professor Yi, the archaeology professor, is Xiao Nai's dad from Love O2O. Or am I seeing things? As for what this novel is about, well, Gao Lan doesn't have a brother. She has a sister named Gao Yao, a tomboy.
Wenwen is very well written, please update it.
