The ways to increase goodwill are: 1. Listen to the singing and watch the performance (unconfirmed). 2. Chat with her (choose the option of "dialogue"), and then choose the dialogue item according to her preference. My sister is proud, so I have to follow her in all the dialogue items I choose. 3. change clothes more. If you can talk to her every day, choose the right option (you can shake her face from the conversation)
