Pure and Loft's relationship begins to grow deeper, while Air starts to sense a change in Pure after returning from France. Determined to settle things quickly, Air tries to clarify her own relationship with Lamp. Meanwhile, Loft visits Pure more frequently, and the two gradually become closer-far beyond the bond of mere acquaintances or siblings.

Air decided on getting a divorce from Lamp and explained it to Juthamas, but Juthamas refused to accept it. Air then went back to Pure, asking her to wait because she was about to finalize the divorce. Pure, however, began to hesitate, unsure whether the one she truly loved was Air or Loft.

When Loft discovered that her brother Lamp was about to divorce Air, her heart sank, for she knew her own fleeting moments with Pure were about to end. With tears in her eyes, she went to bid Pure one final, aching farewell. At the very same time, Air returned to Pure-only to find that the love once shared between them had already faded. Crushed and trembling, Air urged Pure to bare her heart to the man she truly cared for, even as her own world was crumbling for being too late to reclaim the love she had lost.

Pure and Loft, burdened with guilt for hurting Air, chose to part ways and vowed never to meet again. Years went by, and each of them followed a different path. Pure held an exhibition of her work, where she unexpectedly met Lamp and asked about Air and Loft. Air was preparing to move abroad permanently, while Loft had devoted herself to running a pool villa business in the countryside, rarely returning to Bangkok. One day, Pure went back to the familiar restaurant where she used to dine with both Loft and Air-and there, she finally encountered the one she had been waiting for all along.
