Both MY DEAR CAT and WONDERFUL DAYS are long running Family Dramas. Quirky Lovable Characters.. Complicated Marital//Parental relationships.Shady business men and a hint of Romantic Comedy.

The main character and the episode type are similar. The main difference is that GTO is set in a school and IWGP is set in the street.

If you like this kind of movies, you should watch both.

Both films show adaption to life of autistic young person and their relationships with close people. Both films are very warm, touching, humanistic.

Both drama about the short stories of love with the same style...

watching Raak Boon every episode reminds me of Who Are You, because both female lead suddenly can see ghost and the ghost always appear before them to disturb them cause they need help, the ghost gives hint to our female lead to catch the criminal who kill them, and solve the case..
both story involve police and cases, i also think the character personality is quite similar too...

From the same mangaka (Keiko Suenobu) if you liked the atmosphere of one drama you probably will like the other... even though "LIFE" is generaly just about bullying in school life.

Both dramas are more than 30 eps. Both have the whole birth secret storyline and they deal with inheritance of a family company.

Same director, same feel (at least for the first episodes of DS). One has a medical-spy plot with political implications, whereas the other concentrates on the political-spy part.

Same story line, two strangers who suddenly get involved and after that can't get away from each other.

Great acting, a lot of suspense, and although the overall outcome might be predictable for some viewers, the movies are absorbing and kept me glued to the screen.

girl "causes" the death of the man's bride. Man falls in love with girl while trying to take revenge :D lol

Working in tv shop, Dating with younger man, friendships and many similarities ...
