Sad Dramas/Movies with a happy ending

So I'm really into dramas that make me cry but I don't want heartbreak at the end, For example, the Chinese movie Better Days was really sad but had a happy ending. Or maybe a drama like Beautiful World where it was really sad but had a happy ending for everyone. 

Just Between Lovers

Sassy Go Go - it is school drama with many sad stories, but also about frienship and trust. It has nice happy ending. If I cry, it is in happy moments, not sad ones... so I don't know if it is sad enough for you. :)

I love Better Days!! I'd recommend Project S: Skate Our Souls. 

I like this genre too so i can recommend you dramas like A tale of thousands stars, Ashes of love, Birth of beauty, Black, Ending again, Eternal love, Extraordinary you, HIStory: Obsessed, Love and redemption, Mask, Moon lovers: Scarlet heart ryeo, My little princess, Once upon a time, Sparrow, The destiny of white snake, The untamed: special edition, Unexpected. Some of them are not sad through whole episodes but they had some heartbreaking moments and of course all of them have happy ending.
