[With the death of Lena, Yumemi is now down a roommate, and perhaps that's why she doesn't linger too long in her room and instead makes herself busy. First, she checks the Christmas tree and actually finds two presents with her name. Afterwards, she busies herself with sliding a note under everyone's doors or pushing it into their hands when she walks by. It says the following:

Special Activity in the Arts and Crafts Room! Please stop by at 3pm if you'd like to take part! There will be hot chocolate, papercrafts, and a special presentation hosted by yours truly. It will make me very happy if you attend.

-- Yumemi Hoshino

Those who decide to see what this is will find that Yumemi has pushed a bunch of tables together so that everyone can sit together for this bonding activity she's put together, with stacks of bright construction paper, markers, and safety craft scissors (so that no one gets hurt!) as she smiles.]

I have been thinking, and I have come up with an idea for all of us to get to know one another better and form stronger friendships. I think it would be nice if we all sat together and made something each of us like that we want to share about ourselves? For example, I crafted this.

[And here, she holds up some origami stars she made.]

I also attempted to draw some constellations! If anyone is interested, I would be happy to show them to you and provide information about them, as well as many other stories about the heavenly bodies of the universe in a special presentation that I've put together to pass the time here.

[... She misses being at the planetarium and doing presentations with the projector, but this is the best that she can do for now.]
