Romance with a single parent as main love interest

Hi all! 

I'm looking for a romance kdrama that has a single parent as one of the main leads (and as a plus, the other lead getting close to the kid too), so what I'm looking for is a romance family drama, I think? But comedy would be good too. I just finished watching Baby-faced Beauty, in which the second lead had a daughter who the female lead got close to, she was the first "girlfriend of her dad's" that the kid approved of, but because he was the second lead he didn't get the girl. So, I'd like something like that. It can be either way, the female lead that is the single mother or the main male lead that is a single dad. It must have a happy ending. (I found Single Dad in Love, which is also what I want, but I spoiled myself the awful ending before watching and that's not what I want) 

I googled this in many variations going from single parent in dramas to single dad in dramas and any other key words I could imagine but sadly, I haven't found anything. Also, I tried looking here in the forums of MDL, but again, no luck finding what I wanted. 

So, please, anyone can think of something? Anything? Pretty please, and thanks in advance. 

**Oh! Also, I asked for kdramas because that's mostly what I watched, but it could be Japanese too. I never watched any chinese drama or from another country but if the plot of the drama is good, then I can give it a try as a first. 

I'm currently watching Bara no nai hanaya (j-drama) about a single father who is very close to his young daughter. The female lead also gets close to the kid. I've only watched two episodes so far but I can tell it's very cute even though there's also some kind of mystery going on.

Another j-drama that is not exactly a romance (but a little bit of that too) is 37.5 no namida. Two of the characters are single fathers and the female lead gets close to both of them and in the end she'll have to chose who is her love interest...

The j-drama Daisuki!! is not a romance but it's about a single mother who is mentally disabled and her family. It's a lovely, heartwarming family drama so that's why I mention it anyway.

Virgin Road is another j-drama about a single pregnant woman and a guy who agrees to act as her fiancé for her father's sake... I love it!

Here's finally a k-drama for you - maybe it doesn't count as exactly what you're looking for but I have to mention it anyway: On the Way to the Airport is one of my favourite romance dramas ever. The two main leads are not single but they live in what could be described as emotionally dead relationships so it's like they're emotionally single. The male lead is the most wonderful man ever, so gentle and caring and the woman's kid likes him, too but they don't interact a lot.

I'm sorry I couldn't help you more...
