In both dramas a look alike switches places. Unlike many dramas where there is blood relationship between the people who looks alike there is none in both cases.

Both dramas receive messages from the future. The story and why they receive the messages are different.

Both are about a popular guy in school (who is oblivious/doesn’t care about him being popular) and who likes a shy girl with low self esteem (because others make fun of her appearance). Both of the male leads also like the girl from the start, and the ML and FL interactions are always awkward but still swoon worthy.
