No hint, I didn't unlock Neon yet, I was just doing the quest Freedom in the heart, the second step is to go to where people is attracted by music, which I suppose is main street, I try every day morning and noon and nothing. The only girls with hints left are Maeve, which said that is a mission I already did a long time ago but she don't appear on living room night. Taile is the other to see how is she doing after 'Core recharged' and the last Isabel but without Neon, I can't progress on that.
