Saying I love you in Asia might not be that common in comparison to the West, but It isn't always romantic. My family is Chinese and my mum says I'i love you' ALL the time. Does she want to have my babies? NO.
Leon has perfectly good reason to want attention from his siblings and I'm sick of everyone that's saying that Leon wants to f*ck Camilla. I actually quite like the fact that leon isn't that much of a haughty loner and reveals his weakness to his family. It's cute! c';
