I don't remember the feeling

After Pleng(Ferin) and Grace(Puifai) through trials of the heart and found their way back to love, a mysterious accident steals not only Pleng's memories but also the feelings she once held. All that remains is a heart that still trembles whenever Grace is near. With pain, patience, and love, Grace must gently lead Pleng back to what they once had to prove that even when forgotten, true love endures.
