People always grow in loss, and only after loss do they know how to cherish. Many people understand this truth, but if you really want to understand the meaning of that layer, often only if you really lose it, you will understand how unforgettable the pain attached to growth is.
Bridges of Wonderland is a story of friendship, adventure, loss and life-changing youth.

Neither Jesse nor Leslie had any friends.
Les uses his imagination to fill the lonely mind and looks optimistic and cheerful.
Jesse uses a negative attitude to face the current situation of loneliness and ups and downs, in the face of family uncaring, classmates are not friendly, Jesse chooses to use painting to replace childhood happiness.
Thanks to Leslie's appearance, and her optimistic attitude towards life, she successfully pulls Jesse out of the negative world and takes him into the dreamlike imaginary world with him, with a world that belongs to both of them.
However, Jesse seems to have been only attracted to Leslie's fantasy imagination and did not really regard her as a close friend, so Jesse did not invite Leslie to the museum with him. It is precisely because of this move that indirectly led to Leslie's death, Jesse blamed himself very much, believing that he had killed her, and he had ignored this only friend.
Until Leslie left this world, Jesse found that there was no one else in this world who could really make him happy except Leslie, and the days with Leslie changed Jesse's attitude to life, and it was because of Leslie's departure, Jesse's "death escape", the family began to care for this little boy.
Jesse no longer lives as passively as he once did, he learns to imagine this noisy world as a beautiful world of his own.
Leslie, she is very hard to make friends, Jesse for her, can be said to be the most important person in her life besides her parents, she let Jesse follow herself to "crazy", together to create their own world, their happiness.
Leslie was lonely, so she learned to imagine, perhaps because her parents were writers, near Zhu Zhichi, but more because she had no friends, and had long developed the habit of using imagination to see the world. Because of this, when Leslie met Jesse, the boy who could imagine with her and enjoy the happy time after class, she chose to use all her energy to create a country exclusive to the two of them.
Leslie may have died with sadness, because on the day Jesse went to the museum, Leslie went to him to find him and found that he was not there, so he hurried to their exclusive country, and finally did not see Jesse, her only friend, and regretted leaving.
One, Jesse "knew" that Leslie had "broken into" the forest the day after he died, and had even used up all the paint, but that was just the fact that he didn't want to believe that his friend was dead.
Second, Leslie's family left, and it was invisibly said that the girl who had given the boy light was indeed gone, leaving nothing behind, and Jesse's only friend left.
Third, Jesse accepts this reality, builds a bridge over the place where Leslie died, and shows everyone what their "kingdom" is. Jesse wants to tell us that the girl's departure will not let him sink anymore, and he will continue to walk in the path that the girl has shown him.
The girl's departure made him learn to grow, he not only accepted the reality and began to do practical things, but also learned to share, obviously, the girl changed him, the friend changed him.
In the end, in fact, the shadow variety people are very touched, such a cheerful girl Leslie, surprisingly only one friend Jesse.
I didn't think that her imagination was so much related to loneliness, and I thought it was a rendering of childhood thoughts, which should not be bound by the world. But then it turned out that this was not the case, which actually showed the girl's loneliness on the side, and could only be enjoyed by it.
I believe how sad the boy is when he finally knows that he is the girl's only friend, how much self-blame and shame, why he did not really regard her as his best friend...
We always know how to cherish after losing, live in the present, please cherish the present.
