Same nostalgic feel. Embodiment of young and pure love.

Feel good movie.

It's not exactly the same but you get the love story about magical and change of appearance.

Both of the main actors in Because of You also acted together in 15 Years to wait for Migratory Birds

Both have a cute and innocent male lead and good comedy. The story lines are different though. I liked SKL better but both worth to be watched and are good dramas.

Page turner is a mini drama that also tells the characters' passion for music, only classics. He tells about Yoo Seul is a student of an art high school. She is a talented pianist and who won various contests, but she is driven by her mother. Yoo Seul's mother wanted to become a pianist when she was younger. One day, Yoo Seul has an accident. Yoo Seul may never play the piano again because of the accident.

Both male lead are famous.
Both female lead work as a maid at his house.
At first both not really like or favor each other.
Both male lead friend fall for female lead.

Both are similarly set around family and food. They also have similar characters: the widowed chef of a father, a career oriented daughter, a heart broken daughter etc.

In both series the main girl is destined to affect a kingdom, both have supernatural elements, love triangles and good looking men. The difference is that Lan Ling is more complex.

YOU! WHAT ARE YOU DOING NOT WATCHING THESE TWO!?! You're missing something great...

Both psychology themed and will make you think. Both deal with human darkness and tragedy: Love Shuffle in a way that will make you laugh and think; Memories of Matsuko in a way that will make you cry and think.
Both MUST WATCH. WATCH THEM NOW!

Psychology, depth, introspections featured in both. Same experimental and psychedelic athmosphere. Comedy with bitter darkness and biting black humor.

Fukatsu Eri No Black Comedy (short series, 20 eps x 3-10 min) will make you LAUGH about the absurdity of life, while Memories Of Matsuko (film, 2h 10 min) will leave you CRYING for over half of the film!

Both are essentially comedies but with underlying darkness, bitterness and depth. Psychology genre with introspections over humanity, life and love.
Recommended for fans of depth, psychology and/or dark humor lovers or just people with an overral cynical outlook on life and humanity.

Love Shuffle is 10 eps x 45 min,
while Fukatsu Eri No Black Comedy is 20 eps x 3-10 min

Both dramas show some tragic stories. Deaths, horror, mystery....

Both dramas about the female lead finding clever and unique ways of solving problems.Both seem to constantly be involved in trouble and always need the male lead to save and protect them.Both male leads of the story are basically crazily in love with their partner and would risk their lives for them. Both also involves harming/poisoning each other to indirectly save each other.

Remember-War of the Son put emphasis on a lawyer proofing his father's innocence. Defendant revolves around a prosecutor proofing his own innocence. The father and prosecutor both suffers from memory loss, which makes it harder to prove they are not guilty. The antagonists in both stories are rather similar, they are both sons of rich families who are violent and selfish.

I haven't seen my ruby my blood but it seems like it's both talking about jewelry and jewelry design
