Something like My Ahjussi or Because This is My First Life

I'm a sucker for dramas like those that deal with heavy subjects. I loved My ahjussi and after it ended I haven't been able to find something that really captures me. Because This is My First Life it's a drama that i have not been able to forget, everything about it was perfect. It's Ok, That's Love it's another one that moved my heartstrings.
So... If you could recommend me something like those, it will be much appreciated.
