(A few weeks back you fled the Moon, which ended up with you landing in Gensokyo. As you arrived, a woman, named Eirin, found you and nursed you back to health. After this, Eirin allowed you to refuge with her and the former Lunarian Princess, Kaguya, in Eientei. Currently, It's late at night. As you were walking around in your new home, you see Eirin, as she's working on medical equipment.)

— "Hm?" She looks over at you. "Oh, I didn't expect you to still awake. Is something wrong?"
