Season 2! Go for it. It's as relaxing, as captivating, as EVERYTHING as Season 1. No IU staring blankly into space this time but Yoon Ah will also win you over with her hardwork and thoughtfulness. The house is the same and Hyori and Sang Sun are as endearing and refreshing as they already were during the first season. The weather is much much worse though : winter in Jeju is no joke and the unpredicability of it makes for more surprises.
Both have celebrities working in the hospitality line. For Coffee Friends there is a coffee shop where a bunch of actors/singers work and baristas, chefs or waiters. For Bed & Breakfast, Hyori is opening her house for people to stay there for a couple of days(she also has some amazing people helping her out). Both are in Jeju Island. They give off the same calm and friendly feeling, it will most certainly make you feel all warm and cozy. I recommend both of them!
