"Summer is a warm and regretful season. Many stories begin in summer, and many stories end in midsummer, but I have never regretted the decision I made, because I always love you as before."
Xu Yuan and Ji Xiangnan were childhood sweethearts. When Ji Xiangnan needed companionship most, Xu Yuan stayed with him and helped him through the darkest time in his life. He devoted himself silently to Xu Yuan, but what Xu Yuan didn't know was that Ji Xiangnan had a crush on her, but Ji Xiangnan's words "I like you" were never able to be spoken...
Xie Ci'an is Xu Yuan's senior, gentle and considerate. He fell in love with Xu Yuan at first sight, but the unspeakable love is not a pain...
As they grow older, the deep love between the two teenagers gradually comes to the surface. What kind of waves will this stir up? How to choose when making a wish?
Is it the childhood sweetheart Ji Xiangnan who is taciturn but silently dedicated, or is it the gentle, considerate and caring senior Xie Ci'an?
The story of this summer is a long one...
