From Ji Hehan's perspective, look back at the life of him and his brother Ji Yidong.
From the secret heartbeat in the mid-summer of youth to the tenderness of staying together day and night, the tolerance of their family once made them think they could last forever. But a sudden change shattered everything, the family was broken up, power was seized, and they were forced to separate. Even a brief reunion could not withstand the weight of fate.
Twenty-year-old Ji Hehan sank all his love and regret into the deep sea, leaving only unforgettable thoughts for the rest of his life.
Intention: Under the pressure of fate and reality, although pure and sincere love is eventually crushed, it becomes an eternal obsession and scar in life.
