A romantic sim I discovered by chance (doing a search with the word cap), it is set in summer-like weather. The mountains have tunnels dug into them which light up as you are walking through. The tunnels and the trails lead to secluded spots for friends or lovers to sit together. The sim is fairly quiet, most of the people I have seen there seem to write using the cyrillic alphabet (from what I could tell in the local chat), I am not sure which language it was (feel free to let me know).
The sim is rated Mature/Moderate
