I'm looking for a particular drama, and for the life of me, I cannot find the name of it. All I remember is that it was a Japanese drama (I think) about a young aspiring photographer who is an assistant to another photographer when suddenly, a little girl shows up in his life who happens to be his daughter. Her mother has died, and he didn't even know they had a kid.

SPOILER : I remember the last episode being where he had the opportunity to go shoot some pictures for National Geographic and leaves for a year.

If someone could help me figure out was this drama is called, I would be extremely grateful.

Thank you so much!!
