"Wait. My indecision as to which girl to pick out of the harem has resulted in them leaving and doing their own thing? No! I will drag them away by force and prevent them from leaving me."
Of course, I think more "harems" should fall apart by episode/chapter 3 or 4. You try telling a girl "Sorry, I like you, and 5 other girls. Can you wait 3 years for me to decide which of you I like the most? Oh yeah, remember to throw yourself at me every day from now on."
