Sincerity was leaving Sta. Clara, the barangay she grew up in, in four days. His best friend, Markus, wasn't ready to let her go. Not when he hasn't yet told Sincerity how he values her more than just a friend.
For Markus to miss Sincerity less, Sincerity leaves Markus 4 letters; and for Markus to make the last days count, spends it by going to the nostalgic places in Sta. Clara.
Together, both learn to say goodbye in the beautiful and peaceful provincial life of a land of memories.
