It's been a long time since I saw Notting Hill, but the scene in the book store where Julia Roberts is just a girl in front of a guy asking him to love her is very powerful. Especially since he initially rejects her plea. I have seen a similar moment in the Netflix film  Always Be My Maybe with Randall Park and Ali Wong. 

What dramas have you seen in which the FL pour out her heart to ML and turned away, either initially or finally? 

Money Flower - it has a similarish scene to it. Both male leads trick her and it takes her a while to figure out how.
Descedants of the Sun - 2nd lead couple scene is exactly like that. Girl tries again and again to confront him about them again and again but he continuously leaves her standing even when she pours her heart out.
