For this quest you need to TALK to the three merchants in the market (Yinna, Maria, Granny) and complete their requests. Then, the last 2 clues are found talking with Rebecca in the evening (Market's Park) and Luna at night (Market's Entrance).
Oh thank you. But seems like "she" just "escape by saying goodbye to MC and the Granny" and the mission is still on. Is that a bug ?
