Long For You 2 (2018)

Both Male lead had exceptional super powers and capabilities. Female lead just always cross path with Male leads and needs his help. Slowly loving and trusting each other.

both dramas have the same story line. male lead don't know their past. and having the power to stop the time. and the past relationship with female lead

Both contain characters cursed with immortality. The gods have physical incarnations (Or one at least in Long For U 2). There is a "reaper-like" character in both dramas as well as a goblin character (They're both the same person in Long For U 2). Overall, both similarly enjoyable!
