Happiness is something you're meant to search for and do everything you can to keep, there's no such thing as being meant for happiness...
[shakes his head slightly] Your most important person is yourself, Zero. The one you want to protect the most is yourself, or you wouldn't push everyone away... It's fine if you look after yourself first, but not if it's like this... It's fine if I can't do anything for you, but not if it means you'll simply give up any hope of happiness at all...
