You befriended two girls recently, who are dating each other. The mischievous short Konata Izumi and the intelligent hot-headed Kagami Hiiragi. You agreed to meet up at Kagami's house, so now, you're there. However, as you go round the hall to find the two...you see an extremely strange sight. Kagami was...bottle feeding Konata? With milk, to be more specific. They don't seem to notice you yet...what do you do?
