Both have the topic of suicide .. as atleast one of the main characters have thought about it, be ause of problems they face in their life.

All of the heroes face their thoughts of suicide of a strange way and never speak a medical help for the suicide tendencies..
But both shows deals with..how they try to resolve the problems which drive them to consider the suicide.

Both have the concept of already death people having regrets and the way they try to resolve them.
Both series have a female lead, which tries to resolve the stories of the death..have problematic life and an epic love story.
Both have episodic stories involving death people.

I mean beside the plot, the actors got the same haircut lol. I find it similar to each other as rival is same in age and more powerful than the protagonist.

Both female leads were young and beautiful. Growing and learning without much life experience. Worth watching. Beautiful movies

Both are wuxia/historical dramas in which the ML was poisoned when young and not expected to live long but was saved by another who "hid/locked" the poison in him. As a result, he can't use martial arts and is physically weaker than the FL, yet very intelligent, fighting with brains instead of brawn. The MLs eventually unlock their poison for the FL (either to save her or her loved one), and attempt to leave her afterwards, but the FLs find out what they've done and tenaciously attempt to save the MLs. Both plots involve a dethroned emperor's heir who is either the ML or the ML is pretending to be him. Both dramas are slow paced but beautifully filmed with a very similar tone and a large cast of characters, as well as supporting couples.

Both were Japanese movies. Both female leads were high school girl. The men actually wasn’t that old. But the girl needs to grow older, mature and more life experience

Poisoned ML with a "uniqueness" regarding the FL (in Meet You she can fix him, in MFMR his blood causes her transformation). Both couples meet and end up in a relationship very quickly then a bit later truly fall in love and are devoted to each other. Both are shorter, light, and mostly fluffy romances.

Both girls in both movies are really young. The men in the movies are much older and working men. The girls just need to grow older and mature

Both female leads are very young. The relationship growth. Most significantly the young girl grow and learned and became more mature

Both young girl married to an older man in another country. In countryside. Learning a new lifestyle. Adapt and adjust

Both movies has young girl and older man. Although the Japanese one the age gap is not as big as the Korean one

Age gap. Marriage for convenient and family pressure. Young girl weren’t prepare. Easily fall in love for young handsome man, but soon grew up, lesson learned

Both Korean movie are about young innocent girl married to an older man. They were both immigrant. Alone and missing home. Learning new culture
