Both have superhuman powers, set in school, fighting against forces bigger then the local bully and also have a similar sort of feel to them :3

Both feature a main cast of girls with very different personalities living together and figuring out love, life and friendship. They also follow the girls' experiences at university in the case of Age of Youth and work in Renai Dekinai Ryuu.

Both movies are about zombie apocalypse, so the plot is very similar. But the atmosphere in this two movies are very different. Train to Busan is more like a tragedy-drama movie than a horror movie, while I am a Hero is an intense horror-zombie movie with a very few drama. I am a Hero has more violence, blood, and gore than Train in Busan.

Both are zany, 30 minute shows. After School has the energy of the earlier episodes of School's Beauty.

The plots of these two dramas are very similar - two families who live in the same building and hide some secrets.

In both dramas lead actor is Tiffany Tang, who acts a serious but easy going/fun loving person. The dramas' story are similar because main character (acted by a Tiffany Tang) uses someone else's name to go to a family either to find someone or take revenge. Both drama are really strict to the point but with a twist of Tiffany Tang's character's humor. Which allows both dramas to be suspenseful in a good way. Tiffany Tang's historical dramas takes creativity and romance to another level.

both main characters tried their best to achieve their dream even though there were many obstacles and difficulties ahead. They gained many useful experience during the training to make them prepare for the duty as a pilot/ cabin attendant. the drama show happiness, sorrowful, hardship and friendship.

Both are Chinese BL (Boys Love) stories in an ancient setting. One is a short web drama, the other a movie.

Both dramas deal with the female lead growing into herself/finding herself. Also, in both, the female leads have to deal with a hostile working/school atmosphere, are faced with being older than everyone else and have family that doesn't support her dream.
The male leads in both are sweet and funny, not like the usual jerk leads. Finally, both dramas are light and funny, with a lot of heartwarming moments.

The main characters have the same sanse of humour. Both of them are swindlers. The only difference is that one of them is also a magician.

Similar forbidden love story with the charisma of the same lead actor. OSTs create similar feels as well

Both series have the same feel in how they are directed. Both female leads experience a crash scene in where they both loose their memory. Personally, Stairway to Heaven was more of a tear jerker for me, but both series are amazing melodramas.

Both are about broken up couple meeting again after a long time but now one of them has a new partner leading to a triangle

The main characters are a mother and her three daughters. The dramas are around family and both have romance

Wonderful Mama is the K-Drama form of A Moment to Remember. Although A Moment to Remember is a love story, there is no purer love than a mother's love for her children. A mother finds out that she has Alzheimer's and tries to prepare her privileged, spoiled children for life on their own (without her).
