My Sunshine (2015)

Innocent unforgettable first love.. great chemistry.. stories might be different but will leave lingering feeling long after dramas end..
if you like one, you might like the other

They are quite similar indeed.
Both dramas revolve around the relationship between a warm cheerful woman and a seemingly cold hearted man. The female leads both chased after the male leads after falling in love at first sight but the male leads end up the most heartbroken following their separation, not being able to forget their love. Both of the couples break up due to miscommunication and unresolved issues but end up meeting once again in the future. While Crush focuses more on the time before the break up, My sunshine shows us mostly what happens after the leads have met again.

Both are about unrequited love and reunions. Remembering Lichua is amazing I think even better. The male lead Geofrey Gao is so yummy. Read the novel of Remembering Lichuan first before watching the show. Hope english sub are available by the time you read this.

Both dramas have the same actor with unforgettable love story where both leads fall in love in their college time but one vanishes for some certain reason. They met again after many years learning they did not stop loving each other but instead their love got stronger.
