They are both romance that will make viewers cry. Have the same lead actress which is very good in a innocent yet very lovable role.

2 Days & 1 Night is similar to Wild Kitchen in that they both involve travel, food, experiencing the wild, and making friends along the way.

Both Last Christmas and Orange Days are really great romance shows with great chemistry between the leads and a comfy youthful atmosphere. Both shows revolve around a female lead with a health issue. In the case of Orange Days the main lead is deaf and the way it's executed feels very genuine making for great character development.

Intelligent male lead. Have a love/hate relation. Male lead help female lead in studies. Both are set in college environment.

In both a high school student falls for her teacher and the end up together in the end.
My teacher is not manga like compared to Sensei Kunshu and the story is a bit deeper and more realistic.

both male and female leads fell in love the first time they met in the female leads kingdom but then lost their memories of each other. the second time they met they were in the male leads kingdom and is betrothed to one another but male lead already had someone he likes but eventually falls for the female lead.

both female leads do whatever they want, wild, brave and lovable. both male leads are very scheming.

but I would def recommend Untouchable Lovers if you like Good Bye My Princess and because since it's not completed yet and you want to watch something like GBMP you should watch UL since it is completed!

Apart from the fact that both won awards, both portray the stories of people who went through a situation and came out of it with changed mind sets. Both of these experiences taught humility, discipline, a reality check, a new perspective on the 'less appealing' sides to things (like for Departures, the MC learns to respect a job he once thought was degrading and in The Way Home, the MC learns to accept his grandmother and the poor conditions she lives in), teach us the importance of family values and to keep an open mind.

Both of the dramas tells the stories about two people in love who solve problems of everyday life. Problems about work, family, personals problems and more. I think this two stories is wery well done and if you like romance dramas you can give both of them a try.

Both stories aren't innocent and sweet, but realistic. It's about staying together for a long time as couples and whether or not it's a love that can last.

A love story between a 33-year-old woman who does not trust love and a 26-year-old man who dreams of pure love.
He returns to Korea after seventeen years living abroad, but she only remembers him as a kid... It's a similar plot.

The role of female villain in The Last Empress is the role of main female lead in Queen of Ambition.

Though the plot are not very similar, I found it both dramas are slow - burn. The romance between both lead couples are more mature.
