Poop Covered Pen is actually an ordinary pen that Huang Yue Ying gave to Zhuge Liang, when she was still identified as his mysterious pen pal in the Jingzhou Building's toilet. Even though it was just a pen, Zhuge Liang always thought of it as a very special pen and always took care of it. Especially, since he had a cruch on his mysterious friend, in which his instict told him to be a girl. Note: This is a pun, as Shi (poop) Gai Bi (covered pen) is also Skype in Chinese.
