I wanna romance Renee but I have no idea how. The wiki doesn't give me any clue on how I romance her, it tells me something about when I unlock dialogue options about herself and other, but I don't know how i unlock these, can someone help me please? Thanks

it's in the wiki: "After finding the old alchemy book in Wilderness Cave, Kristan can return to Renee and show her this. She will be willing to trade the valuable artifact, so you can try asking for 700, or 1500 coins. You can alternatively give the artifact to her, and that will open up her romance route."
