The girl was stunned to find the sought-after frangipani flower was in the hands of an unknown man. Suddenly his gaze sharpened. Luna turned aggressive. The man jumped in surprise to see the woman in front of him speaking a language that he did not understand. However, when viewed from the signs, the girl looked angry.
