People become afflicted by "mysterious diseases" when their hearts and minds are affected by "the mysterious."
Koto, a girl who produces mayonnaise from her eyes, visits Dr. Ramune, who specializes in these diseases that can't be explained by modern medicine.
She was brought to the clinic by Ramune's apprentice Kuro.
Koto explains that she also cries condiments other than mayonnaise, and Ramune offers her a mysterious treatment.
You're more likely to catch 
a cold when you're tired.
.أنت معرّضة للزّكام أكثر عندما تكونين متعبة
Wenn man erschöpft ist,
erkältet man sich doch leicht.
Eres más propensa a resfriarte
si estás cansada, ¿no?
Eres más propensa a resfriarte
si estás cansada, ¿no?
Quand on est fatigué,
on s’enrhume facilement.
Quando sei stanco, è più facile
 che ti prenda un raffreddore.
Quando você está cansado,
é mais fácil ficar gripado, certo?
Ведь простудиться проще, когда устал?
