Perfect Crime

Both of these involve infidelity, betrayal and revenge. Both have characters that are getting close to the leads under false pretenses, and are relatively mature in content.

If you liked this, you'll surely like the other over ...bcz:
-Same ML
-Unrequited love
- no love, only physical relationship
-ended up falling for each other
- explain stories from all the side
-and more

very same feel while watching, small and big details are same.
also infidelity and complicated love triangle-squares between unexpacted people.
same level sexual content

Both have infidelity themes, mature elements, and passionate attraction, while doing a good job of telling all sides of the story.

While the main theme of Secret is not infidelity, both have darker romances of people falling for people they did not intend to fall for, and intense hate-to-love elements.

Both are stories of people who end up loving the wrong people, with main themes of infidelity, but tells all sides of the story. Sakurada Dori a must watch drama & worth watching.

Onuma Mihono works at a travel agency. After breaking up with her boyfriend of six years, someone she had been thinking about marriage with, she realizes she is already 30. Then, a man transfers into Mihono’s company. It is Ureshino Eisei, the “accomplice” with whom, despite both of them having lovers at the time, she had a physical relationship 10 years ago. Mihono is shaken when Eisei speaks to her with a cool expression, but she resolves to treat him normally. However, when they are alone together, Eisei whispers in the same sweet voice as back then. “Don’t you feel like we’re destined?” The pleasure and desire that revive with their reunion. And yet, even after 10 years, she still cannot grasp his true feelings. Am I the one he truly loves? Or am I just for fun? Even as adults, unable to break free, she sinks deeper into a secret relationship.

they are similar in the intimacy vibes! kakafuka is somehow more mature though!
u should give it a try!

Same ML if you like Sakurada Dori, and he has just about the same persona. In Perfect Crime he's more angry, though, and the romance is dark, not sweet. The FL is the same in that she easily gives over to a physical relationship, and is a bit of a pushover in her interactions with every one else. Both are heavy on intimate scenes.

Similar feel as you watch. FL in both are involved in an office romances with questionable intentions.

Remind me of Kobayashi Katsuya, Sato Yuki & Nishihara Aki drama Shiro to Kuro....& still 1 of my favorite drama....If you like this genre this is a must watch drama/movie. Sato Yuki always adorable since Kamen Kabuto days.

Similarities:
- genres: drama/romance
- cheating issues; forbidden love
- mature scenes, real kisses

Gosh this secret love affairs drama is interesting to watch beside good looking ML & FL. This drama plot is not too heavy & easy to catch up. Not too many conflict. If you like a short & quick drama I recommend this.

Both deal with a female protagonist's journey of self-discovery through an extramarital affair and its consequences.

Remind me of Saito Takumi drama & movie....& still 1 of my favorite drama....If you like this genre this is a muat watch drama/movie. Furuya Robin always adorable since Kamen Rider Saber days.
