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

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
