It stemmed from videogames, one day in 2011 I was checking a download blog that I had seen in an IT course (recommended by one of the teachers), and came across a game called "Shira Oka: Second Chances".
I more or less knew what dating simulators were, having a mostly bad opinion of them ("geez, they're pathetic works for hopeless people"), but the thing is I tried the game and, though it dragged, I completed all routes.
That brought some sense of accomplishment, as well as burnout, so I'm not touching a true dating sim again... but in the process I got to know about this site called Renai.us and checked out some of the games. Funny fact: I called visual novels "ren'ai games" back then. Apparently I thought only romance games were available.
My first Japanese-made visual novel was Yukizakura, in 2012 I think, and I dropped it before completing it because it felt too cringey (that game has serious quality imbalance between routes and heroines. Maybe it's just my tastes). I capitalised on the fact that in that time, new novels were being translated, such as Deardrops, Little Busters or Never 7, and tried them. All those three made me keep playing (you see how there's lack of sex in those? huh...), if it were for the likes of Wanko to Kurasou, I'd have stopped right there.
Why did I jump so eagerly into visual novels? Because the job was done 13 years before by animu and manga. This is another medium in its own right, but feels like an extension of them as the tropes and themes are similar. But now, with English-original, and Korean-made and Chinese-made novels, that is expanding too.
EDIT: My goodness, I forgot about my idyll with Katawa Shoujo and how I followed the development in late 2011 and were among the first people to download it in 2012... good times! I loved the game.
