Seeing Tyson get reduced to only being liked for fetish reasons or a shallow trope feels like a disservice to such a well written character. So I'd like to try and give at least my reason for liking the wolf. Admittedly, I'm neutral towards Roswell and the whole doesn't like Tyson thing never bothered me, so I can't speak from an "anti-Roswell" stance on it. To me, he had valid reasons for the dislike and since he basically drops it past day 9, I think it's moot to hold against him. I feel there are more reasons for being indifferent towards Roswell with Tyson being the easiest scapegoat his fans normally use.
But now, as for liking Tyson. It's a lot of reasons but I'll try to keep it concise (and not simp). His backstory, personal struggles, even dealing with his sexuality, make him the most "relatable" or real member of the cast to me. Him feeling like there's something wrong or broken about himself for instance, it's relatable. His rationalizations sadly make sense and it's always made him the most fascinating character to interact with because of it. The double meaning in his words, or finding the truth of what he's trying to say.
There's his complicated/messy feelings for Dave which for me, makes his the most satisfying route to play. He's someone that doesn't believe he deserves to even be loved, having him finally confess his feelings on day 19 and Dave reciprocating is the most cathartic moment in any route so far. I get that Dean is supposed to be the romance route, but Tyson just naturally fits that role better for me. He's the only one I've noticed Dave initiating affection with past that day as well, even if it's just little acts of a small kiss or something. I'm a sucker for those little tender moments. He easily has the lowest lows yet the highest highs, and most of the moments that actively make me tear up. His admission on day 15 in particular will still break me just imagining that whimper. It wasn't surprising, since the evidence is there if you pay attention, but it was still something I hoped wouldn't have been true.
I could go on, and even now I'm thinking of all the things I haven't mentioned. But I don't want to write an entire dissertation on him. Just know there are reasons to like Tyson beyond a shallow glance at surface level. More reasons than I listed that make him one of my favorite characters in any piece of media. Not just VNs. To me, he's not just "the gay bully character" and frankly by the time the story starts hasn't been for a while. He's not just another "my wolf" clone either, I've no strong species preference to cloud my opinion. Tyson is a complex, very imperfect but redeemable, realistically written character, that has always just been more sad and tragic than anything. Someone that needs patience and love, but has that genuine desire to improve himself. Which I really want to see happen.
The people that fetishize him? Or think his negative traits or red flags are "hot"? In many cases, it seems like they either skim through his route or just ignore the idea of growth or redemption his route has always carried. The unfortunate truth is that they more or less would prefer Tyson's father instead of Tyson. Which if you've played his route, you know how sad that really is.
