I really enjoyed Sly and Single Again well; I'd say it's pretty comparable to Emergency Couple in terms of quality.
I haven't watched these but these deal with an ex (not 100% if the girl chooses the ex in them tho)
Discovery of Romance
My Secret Hotel
I need romance 1 and 2 (but I heard the guy might be a bit of a jerk in INR 1, so these these 2 recs are iffy)
