If you'll like one then you'll definitely like the other! It's both about friends and has the same kind of humor, especially the slow motion fighting part resembles each other! Sunny is a bit more serious though :)

Same genre, different stories. While in High School: Love On an angel is living with the male lead, in Let's Fight, Ghost, obvious, there's a ghost living with the male lead. Both male leads are alike in some aspects...

This is by far, definitely the best version, and majority agreed. It also follows very closely and stays true to the original Japanese manga.

Kurotokage (1962) and Black Lizard (1968) are based on the same Edogawa Rampo novel. Both films are campy and stylish, although the 1962 adaptation includes a few random musical numbers and is considered ahead of its time. Each take on the story also comes across differently since Kurotokage stars female lead Kyo Machiko as the titular character, while male actor Maruyama Akihiro plays the same role, in drag, in Black Lizard. Both adaptations are worth watching!

Both dramas are about a group of women and their struggles with work, life and romance. They also both feature Yoshitaka Yuriko, Oshima Yuko and Tanaka Kei.

Both medical dramas. Both involves doctors who'd rather save lives rather than being a doctor just for the money. Similar plot.

In both dramas, the male leads have supernatural powers. Both have a similar theme of male lead being away/asleep for 100 something years. After awakening, they must re-enter society and learn the ways of the new world as well as find the person that harmed them.

Both are war movies set in 1950 during korean war and both are stories about bravery and sacrifice.

71: Into the Fire is based on real events while Tae Guk Gi is a fictional story

both take place in allboys highschool where close friendships are wrecked and squads fall apart. When one friend starts to ignore the other feelings of inferiority and animosity arise and things go too far

even though I remember you doesn't have supernatural/wuxia kind of genre, i like the feeling of brotherly love of the main male lead to their brother of this both drama.
Ice Fantasy is from China and
I Remember You is from south korea try to watch both drama you'll like it

Though the setting might be different, but it conveys the same "the place where I belong feel".
