Jero and Tom are the young couple that everyone wants to be. On their first anniversary, Jero returns home and discovers that Tom has abandoned him, leaving a box with 300 letters as the only explanation and the ghosting as an answer. The reading proposes to Jero, a trip to the past to meet completely different Tom than what he seemed to be. Each letter sheds light on a extremely unequal relationship riddled with double intentions. And the great love story they lived seems to sink under the title of the "Jero project". But all pain comes to an end and the hope of a new love could be the cure for so much suffering.
