Oh man I can't believe I found this! This was one of the first AVGs I ever played and I was totally confused by "NTR" and the relationship between the two girls. I think in the version I played the two girls were "friends", but their relationship didn't make much sense to me. Anyways, I remember liking this game but I only ever got an ending where you drive off with your gf and get into a car accident in the mountains. Something like that, it's been years since I've played it. I always just assumed that was the bad ending.
