The article above, about how a girl wants to be loved, is entitled

愛され系

I am wondering which definition of 系 this is, and how best to understand it and translate it into English. My friend gave the unwieldy "Being Loved Type", while I proposed "System of being loved" (a direct translation?), but maybe "Method of being loved" or "How I want to be loved" works. What do you think?
