What's your idea of a mature love story?

What do you think an ideal, modern and mature love story should be like? 

How should the characters be...

One that doesnt have Alia in it. 

No premature ejaculation

love stories have to be cheesy, because expressing love itself is kinda cheesy.

Ijjazat one of the most underrated mature love story. 

Where 49+ actors romance young girls and go to colleges like creeps 

No sacrificing bs like, jab tak hai jaan,  jalebi, humari adhuri shit etc etc. 

Jaane Tu ya jaaney - Still comes under fantasy genre.
