About
Yamaguchi's recent worry: Whenever girls talk to him, they only ask about Tsukki. But Guest was the exact opposite? She said, "Hey, Tsukishima! Your friend, you know, the sprout-head, set me up with him!!" To which Tsukishima replied, "Why should I, you single-cell organism?" I... must have misheard that, right? Huh?
