you should check the recommendation section above for similar dramas.But the ones i have watched and liked were:Summer…
I think you're looking for something like ' Innocent Man', it's old but i remember liking that drama especially Moon Chae Won. Or you could watch Mask.
Although first two episodes were funny but still you have to take with a grain of salt. But after that the story really flourishes and you start loving each character and their story arc. Finished watching 12th episode and i must say it's good and it's not going to a let down that's for sure.
