Recommendations

If you like suspense, mystery and psychological dramas, then you will enjoy these two for sure! To start with, White Christmas and Liar Game may not have the same story, but they surely follow the same concept. You will see a lot of mastermind situations, psychological domination, twist plots, a lot of lies said and also you get a lot of suspense when they decide to trust or not a friend or person.

if you liked how Ji Sung in Blood has exceptional skills as a doctor, you might be also interested in Doctor Stranger and how the main lead develop exceptional skills to identify illnesses and cure them, sometimes without having someone to help him or having the proper materials.

Both have interesting plot worth watching =D

Both drama are about secret that lies into dysfuntional families and how they overcome their difficulties

Actually these two dramas were compared in another place. Both have city people coming to farm as an idea to become rich fast after they inherited the farm from relatives. Characters are somewhat similar, at first annoying bratts but then very warm hearted. Modern Farmer is very humorous while Vineyard Man is a bit more emotional. Good family and community related stories. Vineyard Man has a really good and sweet ending.

School boys in blue shorts fighting the good fight to survive high school, family, friends and stay true to themselves.

LoS has more family dynamics.

LS:TS has more friendship/love dynamics.

ok, it's not a direct recommendation, the movies differ, notably in the case of music - Fish Story is about music, See You is definitely not. But there are some links: time span, Hamada's similar role, general climax, different stories involved.

Rurouni Kenshin: Kyoto Inferno (kyoto Taika hen) is the sequel to Rurouni Kenshin. It features the main characters and introduces Battousai's successor Shishio who tries to take over Japan. Can Kenshin beat Shishio while keeping Battousai at bay?

the same main female actress
both are about women who are betrayed by their husband

the drama narrates the story of a touching friends between two friends with a twisted and cruel fate

Both are boy meets boy coming of age story in high school setting.

MB may leave you teary-eyed.

Kekkon Dekinai Otoko is the original Japanese version of The Man Who Can't Get Married. If you enjoyed one, you will probably enjoy the other!

Both are slow starters with well-crafted stories and secret gold stash in the crux of their mysteries.

The same female actress in main role (she improved her skills);
similar plot (even better, more interesting characters and twists ) ; OST really good in both of them; fighting scenes; funny moments; Adjumma (you'll see if you watch it ;D);

The movie is about a father who dies but then gets another chance to bond with his son. He becomes a high schooler and tries to become his son's best friend. HILARIOUS!
