Drama like this pls!

Why do I never get any satisfying recommendations here for the type of drama I want to watch? Like, people recommend me on my forum, their favourite dramas they want me to watch and not the ones I want to see. 

This time I really hope someone can help me. Please, don't disappoint me anymore. I'm really hopeful for this one.

So, I need a drama where male lead is in love with/likes female lead's sister first.

-FL should fall first (important condition)

-Pls no annoying love triangle but I can endure mild ones.

-can be weekly, daily, family dramas.

-can be kdramas/cdramas/Thai dramas

Dramas I've watched like this-

Smile, you 

Which Star Are You From?

My Lovely Girl

My Golden Life (Second Couple)
