Good Romance J-drama Recommendations

It irritates me to no end when people watch bad or cringey manga adaptations and say that Japan doesn't know how to make good romance dramas without a weird plot / bad acting  / badly-written characters. A list to debunk that claim. Of course what classifies as 'good' is very subjective but these are some options from the cable dramas.

I'm in the minority but I love romance J dramas because they don't centre the whole plot around the romance, and add the romance in as part of the person's life story, which makes it more real for me. I mean nobody's life is centred purely around romance or romantic relationships right?

NOTE: Some are 'slight romances'. But I've still included them because the dynamics of those pairings screamed romantic chemistry.

I have a separate list for LGBTQ+ dramas. This is purely for heterosexual romances.

Feel free to recommend dramas I missed out :)
