Yukichi is depressed again today, thinking about all the problems with his owner, Saku. How can an adult human who can't even separate trash make it through life? Doing this and that, Yukichi takes care of Saku's daily life.
I'm a worthless human being that can't even 
take care of myself without you, Yukichi!
Was, wenn ich dich nicht hätte?
Sou uma humana inútil que não conseguiria
cuidar de si mesma, se você não estivesse aqui!
