Any jdorama rom-com without bad characters and love triangles

I recently started watching Neechan no Koibito and really like the drama.

In this drama is around just normal people do normal things, kinda slice of life but with story.

is there any good rom-com jdorama without bad characters and love triangles?

Thanks
