? Extraction code:? 44me？ A throbbing heart is a Thai film, which tells four stories about love and friendship that happened in the summer vacation. This summer, four unrelated stories (the only thing in common is that they have all seen the same movie) are interspersed with stories of youth, excitement, happiness, betrayal, disappointment and sadness, which merge into a sweet and sour youth juice. Although fruit juice will be "sour", it will always become sweet after drinking it.
