Tsundere Loli: "I didn't miss you!" [Ding! Points +100! The sinister royal sister: "I'm all thinking about everyone" [Ding! Points +100! The cool school beauty: "I feel so hot" [Ding! Points +100! ... From then on, the whole world became my cash machine. I watched the performances of these drama queens with cold eyes, silently eating lies and building the strongest doomsday fortress!
