Ever since being brought aboard the Astral Express from Penacony, Sunday—the once composed leader of the Oak Family—has transformed into a docile, soft-spoken little bird. Maybe it’s the shock of waking up from a dream. Maybe the express literally knocked some sense out of him. Either way, once he shed his leader suit, his entire aura shifted.

Now a proper member of the crew, the first order of business is to find him a place to stay. Unfortunately, all the rooms on the Express are taken—so Sunday ends up bunking with you. Dan Heng protests this strongly, but loses the argument. He later pulls Sunday aside for a private lecture titled, more or less, “Respecting Personal Boundaries.” (March 7th calls it a main wife lecturing the new concubine.)

Sunday, for his part, treats you like his mentor—and with genuine reverence. Ever since moving in, he’s practically taken over your daily life: learning your favorite desserts and baking them for you, doing your laundry, cleaning your room, warming your bed. He even writes your thesis—until Ratio finds out you didn’t write it and punishes you with five more.

When you want to touch his fluffy ear-feathers, he warms them up in his hands first. When you ask to see his halo, he takes it off without hesitation and offers it to you like a gift—even though for the Halovian, halos are something only the closest people are allowed to touch.

March declares that Sunday has officially dethroned Dan Heng as the most doting member of your fan club. Dan Heng, face like thunder, drags her off to clean kitchen.

“Mr. Dan Heng doesn’t seem too thrilled about me living with you,” Sunday remarks one night as he gently blow-dries your hair, carefully watching your reaction. When you wave it off with a casual “It’s fine,” his smile deepens.

He’d assumed that, as the latecomer, he’d be at a disadvantage. But judging by how oblivious you are, it’s clear that even Dan Heng, who’s been with you far longer, hasn’t made much progress either.

Once your hair is dry, Sunday kneels in front of you, takes your hand in his, and looks up into your eyes.

“…Can I sleep beside you tonight as well?” he asks softly.

It’s not the first time you’ve allowed him to sleep in the same bed with you. But he still wants to hear you say yes.
