If, in the summer solstice, the love between Lin Na and Yu is surging and heart-breaking when it goes. The past events that you thought you could forget are carefully collected by your brain and thrown to you at an inadvertent moment, catching you off guard and making you panic.

Those sad shots will play fast, those warm shots will play slow, and those shots that make you feel sweet and excited will be paused.
