Second guy (Lead) has loved her all along and befriended her as she crushed on first guy:
Sound of the Desert --- change happens gradually ... she had crush (love) on first guy ... and affinity w/ second guy, turned best friend and slowly turns to real love.
Best Time --- She doesn't realize it until the end, unfortunately ... her obsession w/ her first love was stupid and annoying ... but relationship w/ Mr.perfect lead guy was wonderful and worth watching
Meteor Garden --- crush on first guy .... slowly True Love develops for second guy
She had relationship w/ first guy:Pride --- relationship w/ first guy ... contract turned True Love w/ second guy
Scarlet Heart --- Had love/relationship w/ first guy ... True Love w/ second guy.
Empress Ki --- Loved and relationship w/ first guy ... eventually love the second guy.
Family's Honor --- married first guy (she's a widow)... But True Love is w/ second guy who helps her heal.
In Time With You --- she dates other guys while Mr. perfect is her best friend ... gradually they realize they love each other.
Both guys are leads:
Summer's Desire --- She liked lead, then she liked second guy and was in relationship ... then we don't know who she'll pick until the end
Movie... b/c it's so good and funny:
Our Times --- she crushes on other guy ... as love for lead creeps up on her ... I think they get together much later.
