Beneath the Tranquil Lake.

Three years after an unexpected incident, the relationship between the brother and sister has grown distant. Now, as Rong( the sister) prepares to leave home for college, she struggles to connect with her reclusive, game-obsessed brother, Ray. Unable to communicate in reality, Rong chooses to approach him through a game, disguising her identity in the clumsiest way, hoping to find something she has lost. But perhaps, more than her seemingly withdrawn brother, it is Rong herself who truly needs this journey.
