In both, FL's parents are divorced and FL moves to new city due to her mom's plans. New city is relatively much smaller. FL meets ML and ML's childhood friends and they become friends. FL has male friend from before moving that appears briefly to show that, despite initially wanting to return to previous city, FL now wants to stay in new city. FL has conflict with mom over-determining her life. Eventually FL and her mom make up.

FL in both are not typical high school FL (i.e. not clumsy/bad at school/unpopular/"ugly" + they have nice hair) and are relatively calm/mature/independent for their age. FL in Summer Again is a bit more childish, but reasonably so for her age. In You are Desire, FL (in the high school part) is darker in mood, but becomes brighter as time goes. Both are uncertain about their dreams, but eventually find it.

ML in Summer Again is more bright/cheerful than in You Are Desire, but both are nice, good people, support their friends and FL. Both live alone + have complicated family circumstances. Both have a dream they begin seriously pursuing.

You Are Desire is overall darker and has sadder themes, while Summer Again feels quite refreshing and youthful. But You are Desire has moments that are more fun and youthful, and Summer Again explores some darker themes, too.

Summary:
It's a story about a couple who fall in love (but their love is full of conflict). He is a prince obsessed with achieving justice for his own family (And he wants to sit on the king's throne.). And in this attempt he has no qualms about using people for this greater interest. He meets this girl, this warrior, who he secretly paid for her training (she has martial powers). She doesn't know that he secretly trained her (that he is her ruler). She has a lot of strength of spirit, courage and mercy. He's going to need her help.
He has an illness caused in him by his enemies. However, she is poisoned (she is also sick), but he was the one who caused it and she doesn't know. But even when she finds out, she continues to want the best for him and will act to help him get a cure for his illness. (but there will be misunderstandings in this story. He will think that she betrayed him, but she is trying to save his life. He, at a certain point, will think that she died. (And then there is the most famous scene in the book, which is in beginning of the novel, something that happens later on: he goes to her (supposed tomb) and takes her corpse (which he thinks is hers), (And he even carries her corpse.), in despair because he thinks she died.
There is a lot of intrigue in this story and martial fights, and war (and their love in the middle of it all). In the end they stay together. But Chinese audiences tend to hate characters like that (wishing there is no happy ending). But... I really want them to keep it as in the book, for there to be a happy ending. I love this conflicting couple, but who, at the end of the day, will be loyal to the love that unites them.

In both dramas a murder took place in an apartment complex and all the tenants seems to somehow be involved. Both dramas seem to be very clear in the beginning on what truly happed but over the course of the episodes many things turn out to be more complicated and twisted than they first seem to be.

Love how the main actor plays two very distint characters in both series. However, they are quite different in nature. The Crowned Clown IS a very intense watch, while LSFI is an easy watch.
