Very Ordinary Couple

Kajitani Mitsuki takes care to maintain a modest and refined appearance and has had a fair amount of experience dating men, but in truth, she is extremely uncomfortable with being led by men or engaging in sweet, intimate acts. As a result, none of her relationships have lasted, and she reaches the age of 24 without ever finding lasting love.

Then she begins dating Shinomiya Takayuki, an elite employee at a well-known trading company. However, on their first night together, something unusual happens. Just as they are about to begin being intimate, Shinomiya’s behavior seems somehow strange. In fact, Shinomiya also struggles with leading women and has been unable to overcome his complexes and trauma regarding sex.

Seeing Shinomiya blush and apologize, Mitsuki experiences her heart pounding for the first time. She becomes aware of her discomfort with the expectation that women must always be passive, and awakens to the fact that she has long wanted to be “the one who leads.” Meanwhile, in the face of Mitsuki’s assertive side, Shinomiya also begins to reveal feelings he had kept hidden all along.

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.
