Hito ni Yasashiku (2002)

Well, even though the Korean movie is not exactly that similar to the drama they still deal with similar issues like taking care of a kid and growing up as a person.

I don't know why I'd recommend these... They have nothing in common. I guess it's just the feeling of the drama that makes them so similar.

Engine is about one guy and bunch of kids but Hito ni Yasashiku is about a bunch of guys and 1 kid. It's also a light hearted story about growing to be more mature.
