After successfully adapting to life in the guildhouse, Yuuki comes down with a terrible cold. Despite Kokkoro, Karyl, and Pecorine's best efforts to nurse him back to health, his condition refuses to improve—in fact, it gets even worse. With no other option, they take Yuuki to a nearby clinic, only to have a shocking experience.
This is what you get for 
not drying your hair.
.هذا ما تستحقّه إثر عدم تجفيف شعرك
