I just realized these two dramas have a common point ahaha so I'm writing hihi

The main leads of two dramas time travel and not just a few times! A lot of times!
And they try to stop some death-life events from happening.

The two female leads time travel into the past, they have fun.
The male leadsls deeply fall for the girls.

The genre of these dramas are the same, such as suspense, game.
The characters play a lot of game and try to achieve their missions in order to survive
