Romantic Japanese Drama Recommendation

Hello there!

Could you suggest me some REALLY GOOD romantic J-dramas? I would like it to be a drama where romance is the main plot genre, not a side plot. 

Thank you!! <3

P.S— No mature or 18+ dramas please :) Also, no dramas like Itazura na Kiss or Good Morning Call (shoujo high school drama where its the female chasing after male)

• Black Devil and the White Prince 
• Evergreen Love 

• Hana yori dango – it’s a must see it’s the classical Cinderella story but one of the bests ever done (2 seasons and 1 movie)
• Buzzer Beat – good romance drama about 2 people that meet and fall in love but first they have to find the perfect timing for them to be together 
• Love Shuffle – it’s a story involving 4 couples and how they learn what love is
• Pride – a classic romance drama with a mature couple who grow and learn from each other and also heal each others wounds
• Tatta Hitotsu no koi – a very good romance and it’s a Cinderella story but inverse (rich girl, poor boy)
• Hotaru no Hikari – this has 2 seasons and a movie, and it’s a bout a couple that has to live together due to some circumstances and gradually fall in love
• We married as a job - As mentioned before this one is compared to Because this is my first life. I liked both of them but I'll have to say I liked better how they managed the "contract relationship" at the final episodes here. 
• Soratobu Kouhoushitsu - I like this one, because is also about 2 persons who had their dreams broken about their ideal jobs but with the help of each other discover a new passion in life. 
• Kahogo no Kahoko - This one is pretty sweet and lighthearted, the OTP is very cute and it centers alot on family.
• Boku unmei no hito desu - This one is also pretty lighthearted, the male lead is very sweet and kind and it's totally focused on romance.
