The first VN I ever read was (if you discard some forgettable nukige I once read) Fate/stay night.
I was home due to an ilness, and was just browsing, tvtropes, when I suddenly got the urge to play an "anime-ish" game. I looked, around through some random examples, and I somehow ended up at the Tsundere page. One of the examples caught my mind and more than 1.5 years later, here I am.
