Hello.. I was gonna recommend You Are My Glory and A Dream of Splendor, but I saw in your list that you're currently watching them LOL.. So, maybe I'll try to recommend other dramas.
If you're okay with slow-burn romance, you can try The Rational Life. The leads started as strangers, so you can see their feeling development from the start.
You also can try Love Scenery. The process of their falling in love is sweet IMO.
