Tenshi ni Narumon! EP12 - To Like is to be Liked?

Child Natsumi is staying with Yuusuke and the others at his house. He tells the school he, Noelle, and Natsumi all got sick and his friends take over the committee positions, but they're not buying the sudden sickness and pay Yuusuke a visit. So Yuusuke comes clean and tells them about Natsumi and his friends say they'll help him cover it up as long as he can find the cure. Yuusuke tries to take Natsumi back to the clock tower to find clues but she refuses and runs off. Later, Noelle remembers seeing Natsumi at a grave and that's where they find her. Yuusuke tries to explain to Natsumi that she has to let her brother go, he's never coming back, and she'll stay a child forever if she can't accept that, but all this does is make Natsumi mad at and scared of Yuusuke. She retreats into the (weird) hole in Yuusuke's room, covering it with cardboard and refusing to come out, throwing stuff at Yuusuke when he tries to go in. Meanwhile, Noelle is practicing on the room of the school with the heavy mechanical wings for the day the comet comes. Sara and Gabriel seem a little concerned that Yuusuke is spending so much time and energy on Natsumi, and Lucca tries to point out to Noelle that Yuusuke would probably rather become Natsumi's angel than for Noelle to become him, but Noelle doesn't seem to understand what Lucca is trying to say. On the day of the festival, Yuusuke is fed up with Natsumi hiding and goes to get her out, but she's ready and runs up to the roof. Yuusuke has a heart to heart with her, he explained how at first he thought they had the same kind of sadness over losing people they love, but he'd realized that they were different pains after all (since he is still able to actually see and speak to his parents since they're not dead, unlike Natsumi's brother). Yuusuke and Natsumi both decide to make a wish on the Durian comet to wish for Natusmi to be able to see Fuyuki again.
