Ashinaga Oji-san no Yukue
あしながおじさん達の行方
A man named Haruhi was raised in an orphanage and supported by five men referred to as "Ashinaga Uncles," who send monthly letters and financial assistance for his education and living costs. One of these men, Kasuga, starts searching for the uncles to express gratitude, but instead finds himself living with Natsumi, an apartment building caretaker, and her partner Yasuyuhiro.
