One is Korean Drama the other is Japanese Drama + Movie.
In one the main lead is a girl in the other it's boy.
Both have a time traveling theme. In both it took some time to the main lead to understand the situation… The girl is an actress, she think it's about the period drama she was filming since it's the same period with people with the same name... The boy was in a sort of historic theme park and meet an important historic personage who had a spectacle in the park… So they are both involved with some historical facts particularly for Nobunaga Concerto. They both have some futuristic tools they brought with them in the past. They are plenty of funny moment.
There is more romance in My Only Love Song, and it's ending is happier than Nobunaga Concerto.

Both have time travel and romance. Both are great dramas and On Dal reminds me of Wang So, a little bit.

One simple aspect music and musician and student. In the Hippie is a student too, but hey. There is great music in both and the lead actor in both composed the music and wrote the songs and sung them and performed them. So it's just fitting that it's here. However, Hippie is far from a liar. He's ridiculously raw and straightforward. This is on the superficial level of just music and rock.

I had the same feeling watching them, I think they have much in common. Both dramas deals with family and friends relationships as the main plot. They tell us about Korean family life in a heart-warming and hilarious way.
While Reply 1988 is set in the past, Super Family 2017 is set in the modern times.

Right from the beginning they seemed similar, both have the same main plot of time traveling, they're both cute, short and refreshing as well...

Both dramas have the main male lead lacking in emotion and using it to better themselves in their jobs (ABM=Medical, S=crime)

Although the stories are different, a lot of conversations, wording, and comedy reminds me of Princess Pearl.

They share:
- Cha Tae Hyun
- many guest and cameo appearances

and I think many of the people behind the dramas are the same.

Main plot Height difference. Same theme, similar stories, different perspectives.

Both main male character's lack something because of an event in their childhood.
In Stranger the main guy lacks emotions due to a brain surgery during childhood.
While in Dr. Frost the main guy has trouble sympathizing with other's due to an injury to his frontal lobe as a child.

In both female leads are extremely passionate about food and eating! The imagery and visuals on foods shown in both has a lot of attention to detail and emphasis on the deliciousness of the meal. Make sure you have a snack with you while watching. Differences are Let's Eat is mainly present day setting. While in Weirdo Nara, she conducts experiments which have her go back in time and have historical version of the meal she obtains from her local convenience store. Weirdo Nara eps are very short at just over 6 minutes each.

Both dramas are relations to a romance story with time travel and historical ages. Also in some parts they also experience a change in history. Not to mention the female lead characters in both dramas plays actress who are currently working on the time periods that they both time travel to. Ironic.

Both dramas are about long time friends who don't know their feelings about each other. Bubblegum was more dramatic, the main subjetc was the family. I think Fight For My Way has more comedy and related to other things than family, life, job and relationships.

Both dramas are college based. The male leads in both are super popular and good looking, and we have the shy female leads. The overall vibe is very similar.

Both dramas are quite sweet and has a cute couple as the main leads. The female leads of both dramas are tricked into marrying with someone that has a bad reputation and both know how to cook. In Hua Jian Ti Hu Fang Da Chu, the male lead acts like a gangster, he's rude, doesn't do anything but visit the brothel or picking fights. In My Amazing bride, the male lead has an IQ of a child. Both male leads become desirable husband/ spouse material during the drama through the efforts of the female lead. However, Hua Jian Ti Hu Fang Da Chu is more carefree and fluffy and the leads have a happier relationship throughout the drama. In My amazing Bride, the drama is a little more tragic and the couple faces more obstacles in their relationship.
