Lady & Liar (2015)- Basically the same story as Cruel Romance (EXTREMELY similar so if you liked Cruel Romance you should like this one too)
Summer's Desire (2010)- It's pretty much what you asked for. Ou Chen is the epitome of possessive but I wouldn't say he is "cold" per se... might sometimes come off as that way though.
I'm sure there are more that I've watched but can't bring them to mind atm. I'll update you if I remember more titles.
Thanx I've watch the first one didn't like how they ended it though but loved when they got pregnant but kills cause they Always lose the child (T . T)
