You know the Team should investigate the town of Wayhaven from the Wayhaven chronicles. In it a Lone Detective as a Supernatural team (Vampires) who are practically family joking and teasing forced upon them by a secret government agency and specifically their estranged (Player choice) parent who is in charge of the team who forces the team on them because there is "something special"(magic blood that is supernatural steroids to supernatural creatures) about them. Fun series it's also a romance and a huge chunk of content is removed if you dont romance anyone.
Soo given that this is wayhaven minus the sweetness (The Wayhaven Detective doesnt beat up perps.) I'll give you the same advice I'd give the Wayhaven Author.
1. The more an author tries to push romance on me (Wayhaven literally has the author stop the story to tell you if you dont romance anyone you are speed running to the ending) it makes me not want to romance anyone. Other things that kill the sexy buzz for me. Having interactions and socializing forced on me like it's a playdate (The more you try to make me like the character the less i will), The romance options being the people who strongarmed their way into your life (in Wayhaven i'm most flirty with the weasel of a human journalist), If the stakes are too high (All my life or death doctor characters would punch your teeth out if you tried a Grey's Anatomy hookupwith them). Conversely I find the most attractive characters in these types of stories are the ones who the author hopes are coming across as off limits (The Jokeresque Supervillain Prodigal from heroes rise, the drug dealer from Psy High, The girl blaming you for her brother's death from the fog knows your name, the Bully who disappears for75 percent of the book after being expelled in the first chapter of Creme De La Creme, etc.) might tie into my rebellious nature or my "I dont want people throwing themselves at me." Nature.
2. In wayhaven even an asexual (in deed the author forces you to choose a sexuality in the beginning) detective is friends with the Team by book 2. I get you want some sort of camaraderie but you quintupled down on the loner aspect. So I expect while you can choose to warm up to the team that there will always be a begrudging if not antagonistic answer. A sorta "The team grows on you.... Like a cancerous tumor"
3. Personally I would have turned in my gun and badge by tossing them at Dad's head. I dont know why the animosity is there. Did he sexually assault my lesbian MC? Never was around? Killed a supernatural best friend? Cheat on mom? Miss her funeral? Doesn't matter. I'd have quit because I was PROMISED a Solo career the moment you break a promise to me you are dead to me. So I'd move cross country and become a waitress if dad kept me away from police work until I was begged to come back and given some sort of legally binding contract that gave me what I besides Solo work or including solo work after a set timetable of teamwork. How could that work for a writer who needs the protag to stay with the team? Simple. The Team becomes a permanent fixture in the department (so they can keep an eye on me for dear ol dad) and when I dont have an active solo case i'm sent to work with them because I'm not getting paid to play minesweeper. (Perhaps Dad himself is having 90 percent of Solo cases rerouted to him so he can solve them and leave me to Teamwork)
