I like characters who seem cute, silly, goofy and much frailer than their peers on first glance, joke around a lot, but actually have hellishly painful lives riddled with self-doubt and lonliness/abandonment issues and suffer through it all with a smile, simply because they love their friends so much and want to be strong for them.
I admire the enormous mental strength of these characters. I want to be like them. I want my determination to be there for the ones I want to be with to stand above all my fears and weaknesses.
And when anybody insults these characters for taking nothing serious, being Mary Sues, having ‘no personality’, being ‘annoying’ or, god forbid, getting in the way of pairings, I swear I will defend them to the death.
