Thats, Uh..
After arriving to reply to the letters, Lumine decides to search at Yae’s Publishing house. Gorou says that works, and tells her to come back to Gorou if she sees Yae Miko. Lumine then goes to Yae’s publishing house, and finds lots of people cheering about Miss Hina. After a long talk with all of them, Gorou finally arrives, asking if Yae Miko is at the publishing house, of course Lumine says no, and asks Gorou why he wanted to help everyone. After Gorou’s full response, Lumine decides to just not tell him about the Miss Hina thing.

Desserts Are the Best!
Lumine says she can help Gorou overcome his weakness, and Gorou says that would be great. Asking her where to begin, Lumine says she can act as someone he finds difficult to deal with.

After their failed roleplay, Lumine suggests switching to something he’s more interested in. And so, they change the topic to cake. However, Gorou still acts normal about a cake costing more mora then usual. They then decide to go to a random beach to roleplay as Fatui. Gorou asks Lumine who she’ll roleplay as this time, but Gorou immediately says he smells danger after Lumine’s words, noticing Fatui behind her. When they’re done fighting the Fatui, Gorou asks if there’s anything else to do, and Lumine says she’ll intimate the person Gorou fears most. The two then head back, and Lumine begins acting as Yae Miko, though Gorou says he trusts Lumine, which makes it hard for her to even act as her like that. Lumine then asks Gorou if he wants to get cake, and he immediately accepts saying he’d love that. After they buy the cake, they go somewhere quiet by themselves. Lumine asks if he wants to try her cake, and he accepts, taking a few bites out of it.

Final Remembrance
Lumine tells Gorou to avoid Yae Miko, and Yae’s Publishing House. However, Gorou says there’s something he has to sort out on Narukami Island. He asks Lumine if she can come with him to get a box from the Adventurers Guild, and so Lumine accepts the offer, and Gorou thanks her. When they arrive, since Katheryne says the box is missing, Gorou and Lumine then go to search for it.

When they find the treasure holders who took the box, Gorou tells Lumine to tie them up, and Lumine easily agrees. Eventually, they return back to Katheryne and she gives Gorou the box.
