While studying at university, Zhao Mosheng fell in love at first sight with law student He Yichen. Through various incidents where Mosheng "stalked" Yichen on campus, Mosheng's cheerful personality charmed Yichen, and they slowly became college sweethearts. When Yichen's foster sister Yimei challenged Mosheng for Yichen's attention, Mosheng turned directly to Yichen for clarification, but did not expect to receive a cold response from him. Mistaking that Yichen and Yimei are a couple, Mosheng followed her father's arrangements and moved to the United States to continue her studies. Seven years later, Mosheng - who is now a professional photographer - returns to China, and coincidentally bumps into the unforgettable Yichen. Since the seven years they broke up, many people stand in the way of these star-crossed lovers: Foster-sister Yimei; Mosheng's marriage in United States; the unrelentingly infatuated ex-husband Ying Hui; as well as the financial grudges between the couple's fathers. All these situations continue to affect the two former lovers, but instead, these misunderstandings and challenges give them a better comprehension of the love they have missed over the past seven years 因为有最好的钟汉良，才有最好的何以琛。向来看剧只看脸，奈何剧组忒差钱！。悄悄，是离别的笙箫。这个何以琛，我给满分。。且向花阴觅余簪。我说爱你的方式是润物无声——在情人节聊一聊何以琛与钟汉良。“傻白甜”不好混，唐嫣不如考虑转型。《何以笙箫默》剧评： 当爱情已经桑田沧海 是否还有勇气去爱。你转身的一瞬，我萧条的一生。垂死病中惊坐起，就说我要征个婚。 赵默笙（唐嫣 饰）一直暗恋着高材生何以琛（钟汉良 饰），一段单纯美丽的校园爱情眼看着就要在两人之间展开，就在这个节骨眼上，和何以琛没有血缘关系的妹妹以玫（菅韧姿 饰）突然出现，让一对有情人擦肩而过，之后，赵默笙负气前往美国，两人再无联系。 一转眼七年过去，如今已经成为一名出色摄影师的赵默笙再次遇见了何以琛，此时的赵默笙才发现，自己一直都没有忘记这个自己最爱也是伤害自己最深的男人。可是，今非昔比，如今的赵默笙和何以琛都早已不是曾经的青葱年少，接踵而至的意外，剪不断理还乱的过往，在巨大的压力和阻碍面前，这一对罗密欧朱丽叶式的情侣能否坚持他们的选择，再度走到一起？
