Very Ordinary Couple (2013)

Both movies have some raunchy topics/language and are equally great romantic comedies. They're not close enough to declare plot theft, but otherwise give the viewer a similar range of emotions. Very highly recommend either movie~!

Real life romance, day to day conflict between couple, character growth, good chemistry, like watching couple in real life

Show the reality of couple relationship,started from love each other to growing apart. Started off from breaking up then flashback to first meet.

When her boyfriend was caught cheating on her, Terada Aki moved out of her apartment and into a sharehouse, where she found herself reunited with her first love, Hongyo Tomoya. Hongyo is novelist, but he has recently been having trouble with his writing, and he asked Terada for help - with a shocking proposal. To complicate matters, the other residents in the sharehouse also start interfering in Terada's life.

Both are documentary style dramas, one a series the other a film. They both demonstrate to comedic effect how in the age of cool, we frequently like to portray ourselves as being in control and unperturbed when our actions prove otherwise.

I don't think the storylines are similar at all. I mean kinda, but not really, and only with one couple. I am just recommending it because it is mentioned in the drama. I haven't watched this movie yet, but I hope I enjoy it when I do.
