To be honest, things weren't all that different or more exciting back in the days.:
It's true that Isabel/Marcelo probably had more sex then any other couple especially in the living room. Her and Alma were the only ones masturbating, especially Alma when her and her boyfriend broke up.
More people went ape shit over Nora than any other girl (I personally wasn't a Nora fan), despite her and Kiko having the least sex out of the couples (think Ruslan/Katya except longer dry spell periods).
Alina/Anton used to live in another apartment and literally NO ONE gave a shit about them aside from me and maybe 2-3 other people. Now everybody loves them and I couldn't care less about them.
There was a bit of a scandal in Lora/Max's place when he fucked another girl in the bedroom while Lora was asleep in the living room. Half the people believed he did it behind Lora's back while the other half believed she knew about it. Also their cat is probably the most famous pet out of all the other pets, if you care about that sort of thing.
And finally we had 2 dysfunctional relationships, the lesbians Ana/Danna and the original knife wielding cunt Gia and her boyfriend Ian, both before my time in RLC (I did see a little of Ana/Danna though).
Aside from that, nothing was really different back in the day. Back then I was glued to RLC and used to watch them ALL the time. Now I tune in every couple of days just to check in. I don't think "boring" is the right word to use in comparison between now and then. RLC is exciting at first because it's new, but then the allure of it fades and it just becomes ordinary. A new couple will move in and they'll grab everyone's attention for about 18 minutes before they themselves become ordinary (see Efim/Diana). I made a post last year about the same thing right before Valera/Angela moved in talking about how I think I'm officially done with all the couples but here I am still watching and commenting and calling other people out on their shit here.
