Many workers struggle with the Monday blues. However, Yuri and Oshiro find that Saku comes into work every Monday at the top of her game. Perhaps she knows of some kind of secret countermeasure?! In actuality, Saku only thinks about work and Yukichi.
So I merely need to 
take care of her myself.
Ich muss die Dinge wohl
selbst in die Pfoten nehmen …
Pues basta con que me ocupe yo de ella.
Solo tengo que ocuparme yo de ella.
Alors, jusqu’à ce que je puisse
m’occuper d’elle,
Se è così
Então, é só eu cuidar dela eu mesmo.
Поэтому мне нужно
взять заботу о ней на себя.
