Both are Chinese dramas with a love story based upon time travel and changing fate.
..................................

Both are mini dramas with the same actor and actress as the main couple. In both dramas, the ML dies or is presumed dead, and the FL travels (to another city or back in time) to encounter him again).

ML trying to avenge his best friend death, FL being rescued by ML, action&investigation, crime organization, etc

Both have the different "faces" different "actors" playing one character
Tho from the names one is romcom and another is death?

Drop whatever you are watching and head over to Cdrama land to watch Meet Yourself. It's all about the community, the families, the moral dilemmas, the lovers, the scenery, and the amazing dialogue--very cleverly written. The characters speak and act from the heart. Like Hometown Cha-Cha-Cha the ML and FL are mature and are capable of (literally) hours of interesting banter as they find their way to each other. The supporting cast members are wonderfully portrayed.

same vibes: including business and money

They're very similar in the sense that in both dramas they're going after a large corporation. Both female leads are similar in character.
Also both leads are in the law industry.

Well it's the same FL and the subjects are intimate ones so they are similar watches although Hit the Spot is easier to watch

Let’s add this one for the ‘possibility of phi nong’ both series shows that ‘childhood friends’ could still stay as friends without getting certain feelings involved… as simple as that but we gotta i crease the possibility shall we..?

This is a remake of this drama. A story that follows two couples who mistakenly find themselves in a marriage they never expected and gradually grow in love and trust over time.

Opposed to marrying the princess, Mei San Shao pushes Xiao Wan Zi away in hopes that she'd willingly retreat. Meanwhile, the king has arranged a marriage for Lu Ying Yao, the daughter of the 9th prince. However, bandit Xiao Bao Ye mistakenly takes her as his wife.
