basically 1Q = filming day! More specifically, each Q (stands for queue) represents one set of scenes recorded, generally in the same location. On some occasions, a Q can take more than 1 day to be completed, but usually 1Q takes 1 day. A 12 episode show can be about 20-30 Qs long, depending on many factors. We don't know how many Qs Love Senior will have, but the last one was Q14! Hope that helps :D
i ask myself that all the time... was looking at the posters and it made me so sad, we could have had it all
a couple months back, the official twitter account said that they are still working on it, but they've gone radio silence ever since. the actors also haven't said anything for a while. i doubt they scraped it completely, but i do believe we might not get 4 shows as initially planned. i strongly believe they SKIU will come back, but with significant changes. we can't be sure until there are official announcements, but i will keep an eye out :(
CEO said that filming is delayed indefinitely. they don't want to keep setting a date and delaying it further. crew is working on the season 1 script, casting of side characters and promotion events with the cast. i'm hurt, because this is one my most anticipated shows, but on the other hand, i understand it's a new company, and the crew is very passionate about it, and wants to give us the best possible results. it's also a very ambitious project, with a lot of characters and stories. in the end, i think we would all lose if they rushed it. it still hurts, but i will be waiting for as long it takes, i believe it will be one of the best ones
