While You Were Sleeping
This is a Christmas movie, but it also works well on Valentine's Day. It takes place in the wintertime in Chicago, when transit worker Lucy Moderatz (Sandra Bullock) pulls her crush, Peter (Peter Gallagher), off the train tracks after he falls and hurts his head. Peter falls into a coma, and his entire family believes he and Lucy are engaged.
Knowing that Peter doesn't even know her name, Lucy agrees to go through with it and spends the holidays with Peter's family while he's unconscious in the hospital. She falls in love with Peter's brother, Jack (Bill Pullman), while he is sleeping. This sounds like a lot to happen in one movie, but just trust that it’s a good one.
