Two different story but so similar, they are magnificent for :

- a beautiful and original love story
- know an uncommun disease
- very moved, prepare tissues !!!!
- (the best according to me) : only one love until the end

Both are similar in the aspect where the sisters swapped when it was needed to defend the one who was been bullied.

Special parody episodes of the original show (shows all the characters together). You don't have to watch season 2 to watch this. It isn't strictly necessary for understanding the show's plot.

Both short series are about a couple of friends who are afraid to become lovers. Both couples start to live together and it shakes balance of their relationship. In my opinion Soundtrack#1 is strongly inspired by You drive me crazy.

It's the sequel. While the second part is not as funny as the first one, it's still very good. The second part calls out more BL drama cliches, but it's also a tad bit more emotional than the first part.

The pairs have a similar dynamic, and there are a lot of similarities among the male leads..... plus the potatoes!
