In both dramas an older girl meets the younger boy she knew, now a young man 5 years her junior. Love blossoms.

Both male leads are princes with honourable and strong characters, physically and intelectually that protect the female leads when need it, support them when needed it and match them in wits, skill and strategic thinking. All leads in their own way aim for peace.

Both dramas have male leads with torturous pasts in different ways that fall in love with women that see the goodness in them but they push them away to protect them from their perceived corruption of their lives and hearts. Both male leads have shady pasts that they try to overcome to become the best version of themselves to feel worthy of the women they love for they are the light to their darkness.

Both stories are extremely similar in the way that the male lead is stronger and protective of the female lead which grows into her own self and into her abilities as the drama progresses. It's interesting how Xiao Yi Qing resembles Wuji so much and how Jing Rong is so similar to Fu Yao. Really good stories!

Another YG Survival show where Win: Who's next chose between two teams the one that was going to and did debut under the name Winner.

Both are YG survival shows. Mix & Match was iKon's and YG Treasure Box is for the still unnamed new boy group to debut in 2019.

Hana Yori Dango is the prequel of Hana Nochi Hare. Both stories are set at Eitoku Academy, an elite private school for rich students. Hana Yori Dango has the F4 and Hana Nochi Hare the C5, whose leader idolizes the leader of the F4 Domyoji.

In My Teacher a student falls in love with her World History teacher and in Majo no Jouken a Math's teacher falls in love with her student. In both dramas their love is returned.

In both movies, the main characters receive a letter from their future selves about events that will take place in their immediate future and with that knowledge try to change it.

Both are school dramas, both have female leads with crushes on the male leads and in both, the male lead rides a bike.

Both variety programs are from YG, except here two teams, team A (Winner) and team B (iKon) compete for a chance to debut. It's the prelude of Mix & Match.

Mix & Match is also a survival show, a YG one to select the final lineup for YG's new boy group iKon.
