1. i don't necessarily think you have to write only about your bias...? the very first kpop fic i ever wrote was hanchul and i wasn't rly a heechul or han geng stan but they were cute to me...i went back to look at my exo fics and i wrote a bunch of baekyeol, taoris, fanxing...all pairings without my bias... and if you look at my svt fics too, i've written and really like jigyu and boohao...i just write fics for whatever interests me, whatever i want to explore, and whatever stories come into my head...i don't really kind of think of a plot and then pairing separately, whenever there's something i wanna write they usually come hand in hand and a lot of the time i think it would be impossible to replace the characters...in fact i think that's really important to me, that i'm writing something that best suits the given characters' behaviors. but i have a lot of interests so this idea that i would only write about my bias is weird to me...idk if that's what you meant.

2. a lot of my fics are wonhui. so of course a lot of my fics are going to be about wonwoo...?

3. i write a lot of wonwoo fics because he's my fave writing muse. he's someone with a lot of layers of intricacies and complexities and i really love digging into them and bringing out certain sides of him in stories, thinking about "what if" and putting him into strange scenarios and trying to imagine what would happen thereafter. he's someone who has a strong internal logic though, so i think i can satisfactorily complete a story with him, not necessarily saying "this is something jww the real life person would do" but at least being able to think to myself "the ww character i have built in my head based off of jww remains true to that character throughout this story". as a character he's a lot of fun to explore for that reason, like putting together a puzzle because even tho solving it doesn't mean solving him or figuring him out, there are ways that puzzle WON'T fit that are more evident.
further, his narrative voice i think is most easy to slip into. junhui, for example, is someone who to me doesn't dwell too hard on complex thoughts and feelings, not because he doesn't have them, but he can often gloss over more knotted aspects of his life for the sake of harmony and positivity. he's a lot less internal, i think you can still read him and his actions and understand him in very nuanced ways, but writing him is VERY show don't tell, like super show don't tell, which i find a satisfying storytelling method as a reader, but it's a bit more difficult as a writer. he's a really flawed person but sometimes it's a bit difficult to convey that from his pov. on the other hand, wonwoo is much more cerebral. you can write at length about his internal monologue because he's someone who focuses and lingers on those thoughts and chews on them for a long time. i think it's easier to convey wonwoo's flaws, even if he's not personally acknowledging them, because he spends a lot more time with himself, so to speak.
i guess i also find a lot of things about wonwoo relatable...? i can take on his pov really easily and speaking from third person limited on him feels just like wearing a second skin, it fits easily, it's smooth, it's a lot of fun, and i love it. i wrote about this a little bit in april of 2016 and honestly it still applies...i REALLY like him as a character and i don't think i'm alone in that http://manzeonfai.tumblr.com/post/142943875658/9-12

4. i feel like those two things are not..."aka"...like not equivalent...i didn't end up writing a lot of wonwoo fics because i'm obsessed with him...this i feel like totally ignores the narrative where i became super endeared to mingyu and wrote a lot of my stuff based on that love for mingyu which translated into wongyu fic...i ended up writing a lot of wonwoo fics because i'm obsessed with WONHUI. i feel like spinning it to be about wonwoo is a bit disingenuous when it's clear how much i love wonhui and that's what started everything...

5. i don't know if you intended the question to be like this but the "why are you so obsessed with" sentiment is really negative...i don't understand...am i not allowed to like wonwoo...??? probably from about mid 2015-mid 2016 wonwoo was one of my top 3 fave members of svt...that top 3 changed a lot but jun has been at the top since 2012/2013 and wonwoo spent quite a bit of time on the podium. if you want to know why i like wonwoo...i mean lol there are thousands of wonwoo fans out there i don't consider myself one but i think you could ask any of them and i'm sure they'd give you tons of reasons??? last year i wrote this essay on top 3 things i like about wonwoo tho so... https://pastebin.com/raw/SP45p53K now that i'm thinking about it tho i want to add more like how he's soooooo introspective but can be weirdly self-unaware and it's really endearing that he has this like image of how things are in his head/how he wants things to be. he's someone i think that really is about details, and you can watch wonwoo a bit and get one side of him, but watch him longer and get something completely different...but anyway like loads of people like wonwoo i feel like i am allowed to like him too, no?
