Every time I have to answer this question my mind goes blank. Who am I? Not quite sure, really.
Let's start with: why am I a Sweetbean? That's really easy, actually. It is all thanks to my incapability for naming things properly.
I was once babysitting my younger cousin, she was watching a cartoon show called "Milly & Molly"; and there, there were these first time parents who were struggling to name their baby. By the end of the chapter they resoluted to call her ⋆˙⟡Sweetbean⋆˙⟡ (or something like that).
For some reason, my teenage brain thought it was a really cool name and that I should take it, so I did. Besides, those were my my favorite sweets at the moment.

Then, there's my AO3 moniker LovelyGirlFromAVillage. That one is because I was born and raised in a (gentrified) small town, which, I believe, shaped who I am today. I'm, most of the time, naïve and trusting. And I've got this blind hope that one day, we- as humans, will learn to be more compasionate and caring to others - through education and revolution.
This mindset is heavily influeced by the place were I spent 20~ years of my life: a dull small town, where time seems to never pass, which is both reasuring and infuriating. In one hand, the tranquility of this place failed to teach me how to be more careful; there were way too few people who could truly do harm to me. On the other hand, there's the gentrification rising prices and dispossessing people from their houses, as well as entitled tourits flooding the town, behaving as if the place was theirs.

Living in a place proclaimed as "Patrimonio de la Humanidad" turns you into something to be looked at, as if you were some sort of wild animal in captivity; your life turns into a sightseeing: the park where you exercise, the church your mother visits every Sunday, the street you walk home everyday...
At some point, it becomes infuriating, especially since I come from a poor country. However I'll admit it was my biggest worry. I used to be middle class under my mother's wing, I'm what one may call well read and it was always safe for me and the rest of guys my age to start up riot in the name of justice and be somewhat heard. Therefore, I developed a way too optimistic view of life - or so I believe.

In Summary

I don't want to make this introduction more tiring than it already is. In summary: I'm a naïve person, I'm passionate and sweet, and a crybaby most of the time.
Although, besides my naïvity and melodramatic view of life, none of my so called sweetness is portrayed in my writings. I prefer being uncomfortable, bold, gory, nausating, pornographic, violent, and so on and so forth. That's simply because I love finding beauty in these "horrors", also because I'm a lewd and I'm not really sure what happened at some point in my life (maybe nothing), but I simply enjoy reading that sh*t.
.... So, I guess I'll just say: dead dove, do not eat.
