Kare, Otto, Otoko Tomodachi

The story follows three very different sisters in their very different love stories.
The stories are very well written. I will agree with other comments that the scenes of domestic violence are a little bit too obvious and extreme, but that's an unfortunate consequence of the dorama format, as there is no time to develop the tension. Nevertheless, I think they were some of the most realistic ones when it comes to jdoramas.
On the other hand, I really enjoyed the fact that the stories are not the typical material you usually find in dramas, and the characters felt more real.
The stories and characters are interesting and make sense until the end, and you will gladly follow the three sisters through the changes in their lives.
