Question about Viki

Hello everyone. I hope everyone is having a great day.

I've slowly started to get really engrossed in k-drama and on and off i hear people in the K-variety sub and here as well talk about the viki app and their huge library of content when it comes to asian content.

My question is that I see on their site that for a lot of shows they have mentioned FREE EPISODES. I want to know if these shows are completely free to watch or is there a certain limit to them? Also what are the benefits of buying the viki subscription? Does it only unlock the latest shows?

If someone could give me some deep insight then it would make it a lot easier for me to decide whether I want to get a subscription or not. I primarily only use netflix to watch k-content and I love to watch both dramas and variety shows with idols.

I hope you guys can help me clear some of these doubts.

Thanks.
