A really good revenge drama with happy ending?

I'm looking for a drama like 'Came, Jang Bo Ri' or 'Angel's Revenge'. I don't care about the number of episodes (30,40,50,100 or 120). I loved 'Person who gives happiness' too but I really hated 'The promise' (I don't know why but I was so disturbed that after I couldn't see more kdrama).

I don't understand If I like MAKJANG or not. I like cliché, family drama, secret Birth , hate tourns love, Rich man and poor woman, strong famale lead ...  I can't watch a drama with sad ending, I can't. I love melodrama when the drama end with a happy ending. I can endure if I know the story end well.

Please help me to find a good drama ^^

Maybe Secret

I know this but it seems too sad. I loved the leads in 'kill me heal me' so I have this drama in my plan but I don't think I watch this now. Thanks
