When Amber Liu finds herself surrounded by friends who are beginning to settle down, she is faced with the possibility of finding her true love. It all boils down to one name: Krystal. It must be fate then, when she once again sees Krystal Jung, her ex-girlfriend from 3 years ago with whom she had the best memories with. Amber and Krystal were a perfect couple, and were engaged to be married. It all ended at the altar when Amber had a bout of cold feet and left Krystal alone in the aisle.

Now, Krystal has no recollection of Amber, having acquired “amnesia” shortly after their separation. Amber sees this as the perfect opportunity to pursue Krystal again, and be able to undo all the mistakes she made in the past, by offering Krystal the best memories she could ever have.

True love is difficult to resist, they learn. Just when they find themselves ready to commit to each other, the pains from the past catch up with them, challenging them to finally own up to the mistakes made and lies said, and eventually realize what it is to forgive and forget.
