Of course same tittle
Same time travel
Same saving of lives and changing destiny
One of my favorite kdrama of all time.

The ML is the one who travels 9 times with the use of incense instead of candle .
At first I thought it was a remake

The story somehow relatable. They started to have friendship then falls in love quickly but then the fate has started to intervene so their relationship didn't work as expected... In the movie 20th Century Girl, the FL and ml their relationship didn't work because the ml has to leave and live in New Zealand yet on the other hand , the story of Us and them also the relationship didn't work for them because sad reality intervene so the FL has to leave.

Both movies have a sad ending that will make you ?

They are both similar in many aspects like stories about school life, teenage drama, also about cheering squad. If you happened to love Sassy Go go you will surely love this drama ... Both Male leads are charming !!!

School 2013 is one of the installment of School series. It depicts and tackle s uthe life of every student's journey—stress, family problems, pressure of their school works, obligation, bullying, career path, friendship, and their personal growth. Although this series doesn't focus on romance but surely you will love the tight bond of friendship that they form especially the bromance of real life bestfriend —Lee Jong Suk and Kim Woo Bin...
You will surely love this drama.. And also their teacher is my ideal teacher ( I am talking bout Jang Nara's character) ??????

Both dramas deal with mental health issues. The female lead of the drama is also the titular Psychologist who is also responsible in dealing with different patients with different Mental disorder. The Male lead of the drama is a novelist but at the same time co hosted a radio show. Both dramas, Male lead helped cope up the female lead's issues of their health when it comes to anxiety, depression and heartbreak. Same goes with the female lead act as a friend, lover and a doctor to ML.
Both dramas has some similarities when it comes to themes, romance, healing, mental health and many more.
