House of the Sun Vol. 12 (Kodansha, 2017)

I know more than anyone how much reaching out a hand can save you. If she's alone like that, I have to return the favors given to me somehow... even just a little bit. “Won't you come live with me?” asks Mao's birth mother, Yuzuno, appearing suddenly. Mao knows that she's selfish, but she can't ignore the fact that her mother is also all alone. When she was all alone, Hiro and others reached out their hands to her. She feels like she has to support her mother in the same situation... What conclusion will the struggling Mao finally come to...?!
