After having his conversation with Zero, Yuki headed inside the dungeon even though he had a lingering feeling telling him to turn back and enjoy some with his two new friends.
"Wait what am I thinking? Did I seriously believe that those two would ever consider me to be their friend? Even if they did, I would never call them friends of mine. I've dealt with this type of friendship in the past and it only led me to a whole lot of trouble. Even when things seemed to clear up and I had gained a family, it all came back to haunt me. I'm incapable of making friends," Yuki thought to himself as he walked through the entrance of the dungeon.
