How I start,first I start watch this because of xiao zhan,in first episode xiao zhan oly appear few minitues but I already addict to drama,this drama plot is soo good and I want to talk about renmin she is very beautiful she have cute look some pepole like to brainwash others saying she is not beauty but when you watching drama you understand she have very suitable look for drama,theiir chemistry develope is very strong,first they only have master student relationship so we don't get romantic feeling but when one by one epi we clearly understand how their chemistry build,I love it I saw lot of viewers first have negative review chage their mind like me ,both main couple are such a excellent actors and side character also best
