1. They travel time through car accident.
2. Time travelling exposes the real murderer.
3. Intriguing but not frustrating.
4. You'll crave for lead character's chemistry and love it.

•Both have secrets.
• Rich and Powerful people.
• Woman takes stands for eachother.
But I prefer Mine better cuz Penthouse 1 was so new and exciting others part were too but not in comparison with 1st one. Mine has its own suspense and thrill but it's leaa stressful as they all aren't that cruel to kill anyone who gets into their path. Women are rivals at first but for their child and family they team up and support eachother, penthouse lack this. Mine is funny, emotional and sweet, penthouse has these qualities too but for me Mine >>>>>Penthouse.

The only similarity is that they are reincarnated lovers and both think that the other one destroyed their family.
Both dramas are very very different from each other except the reasons above. While bulgasal is a revenge, suspense, thriller drama with a little bit of Melo and romance, "from now on showtime" is a rom-com, lighthearted drama with some ghost and revenge plot.
But both are very interesting drama. Even when Showtime is still on air i recommend it cuz its not looking like it will disappoint it's viewers, and am loving it do much.

•Both are fresh and unique lovestory.
• No unnecessary love triangle and cliche.
•Supportive characters have their own story.
•Beautiful dialogues. Funny and relatable at some points.
• FL loves ML but they are their own first priority.
• FL don't hesitates to take initiative for kissing or expressing love. They're not coy but clear about how they feel.
• ML are understanding. Also they are good kisser.
• Both are beautiful drama and deserves little more attention and appreciation.
