Romance dramas

So I've always proclaimed to hate romance dramas but the last couple of days I've marathoned Boku to Star no 99 Nichi and holy shit I loved it. I'd like to get in the genre but there is soooooo much of it and there are certain tropes I cannot stand:

- broody/moody male character who insults the female character
- typical genki girl winning over the moody guy
- angst! I hate it, any type of angsting over 'does (s)he like me or not aaaaah'
- melodrama (I enjoy rooftop prince but the whole omg he looks like the dead guy is he or isn't he and oh no evil stepsister GETS ON MY NERVES)
- the girl having no personality or backbone whatsoever
- one girl, multiple guys, I prefer just straight out focus on two people
- tearjerkers, I usually don't mind them but right now I'd rather not watch one

Things I however love:
- couples that just bicker, a lot 
- they don't start out interested but along the way they're like well hello romantic feelings
- lots of comedy
- lighthearted, just something that'll make me smile
- a girl who's not all flustered but is determined and isn't afraid to take the first step

I'm talking about a guy/girl romance here but fcourse I would also love to see a romance drama with a homosexual couple but I'm afraid dramaland is sadly lacking in those? 

For these reasons I'm kind of reluctant to watch a kdrama and I prefer jdramas, hence this question. I don't care which country it is, or if the leads are particularly attractive or not. I was considering From Five To Nine? Or Fake Couple? They sounded pretty funny and lighthearted but I'd love to hear your recommendations! I'd welcome any kdramas too of course but as said, I want to avoid melodrama and such and to be honest, I haven't found a lot of kdramas lacking in melodrama. Thanks!

Taiwanese drama Marry Me or Not pretty much has all of what you're looking for, only it's still airing and I can't guarantee it will stay that way till the end. For jdramas beside the ones you mentioned I recommend Date it's pretty hilarious. I'd recommend Full House thai ver too but it isn't really funny.
There're several asian dramas with homosexual contents that are not pure fanservice unlike most BL jdramas, but they do come with angst (at different levels for each):
Lovesick the series (thai drama)
Hormones the series (thai drama)
Crystal boys (tw drama)

Oh, what I meant by thai is Thailand not Taiwan, sorry if I confused you. Then you may have to scratch Crystal.Boys, it's realistic but in no way lighthearted. I also want to add another taiwan drama Drunken to Love You for romcom

Date - Koi to wa donna mono kashira 
Orange Days
Natsu no Koi wa Nijiiro ni Kagayaku (there is some angst, but I guess that in their case it was normal)
and maybe Love Shuffle (there are 4 couples, but it's worth watching)

I absolutely loved Boku to Star no 99 Nichi too! Here are a few drama's I enjoyed that gave me similar feels;

That Fool (kdrama)
I do, I do (kdrama)
Nagareboshi (Jdrama)
Star no Koi (Jdrama)
Celeb to Binbo Taro (Jdrama)

Hope at least one of these suits your fancy! :)
