People said Lin YuShen is too old pairing him with Zhao LuSi but I think this is appropriately cast. As a businessman, been around the block for a while, YuShen age was great for the role. LuSi as a talented beginner chief was supposedly a younger girl. I like them both in this drama, they tried to develop their feeling to each other by conquering disapproval from domineering mother in law to be, differential financial/economy status, age difference (yes, it's addressed in the drama), as well friendship (LuSi was being loved by her peers while YuShen got no friends at all). I love it when he tried to do everything to win her over again and again...that's we call man with purpose. It made sense, man with his age (supposedly on his late 30th) that never been close to anyone, he won't let go the love that he just found. LuSi is always the cutest.

They took as a challenge when Mom who disapproved with their relationship, to prove they have genuine feeling for each other, that she loves him for himself not for the money or social standing, she's capable to earn Mother-in-law trust and approval, she has the strength against all odds. They have happy ending...
