sweet home 2 is the continuation or ' second season ' if you will to sweet home. the cast is of course the same or mainly similar regarding the main cast and some/most of the support roles.
there is a high chance that they are both like the trill drama or series based on thriller with the unknown creature that makes the series very interesting and one of the famous actor also play a role as a lead character in this series
Both dramas have a similar vibe and people have to fight for their lifes as they are in the grave danger. Also the work is apocalyptic and seems to come to its end. In DAS one day the spheres appears and try to harm people and it's the same in SH where monsters appear.
If you enjoyed 'Sweet Home,' I recommend diving into 'Hellbound,' as both series share a gripping blend of intense storytelling and supernatural elements that will keep you on the edge of your seat.
Both apocalyptic and heart stirring. Each has the perfect amount of thrill and danger while retaining themes of family and romance while battling the urge to survive.
