I enjoyed Smiling Pasta too as my guilty pleasure. I also want to put in a shout out to Summer Desire as well.
These 3 dramas I've watched and rewatched bits of over the years.
1. They Kiss Again - really liked it better than the first drama, but it was also good. But this had lots and lots of kisses, a deeper connection between the leads.
2. ToGetHer - loved the music of this drama, and Momo is such as special character for the heroine as she's different, spunky, but is confident as well.
3. Fated to Love You - yep, it does go off the rails in the last episodes with unnecessary plot twists. But I enjoyed the drama, the angst, and the story overall.
and honorable mention: Murphy's Love of Law - I just completed it and enjoyed it.
