For me, it's more satisfying to watch the MC and the love interest fall for each other over time than to start with a scenario where one of them already has feelings. I think that only really works in a comedy-focused title, like Cupid Parasite. Otherwise, it actually kind of annoys me and makes me put that route off until last lol. I remember finding the constant pursuit of the protagonist by Kazama in Hakuoki and Tomomori in Birushana really eye-roll-worthy. Like, hold on a second—you haven't even taken them out for dango stall or gotten to know them properly yet; slow down! Let's actually get to know each other first! (Just for the record, I like both of them, but that "stalker-ish" pursuit style is a big no for me lol—if I were Chizuru or Shanao, I'd run far, far away from them XD)
