As células de Yumi (2021)

both have 2 seasons and each season had different male lead
both can make the audience believe that the first ml is the ending for the fl which is not

One of my favorite quotes that really made me think came from Yumi Cells "relationships teach us more about ourselves than the other person". Both have very strong relationships that were not meant to be.

Both dramas are psychological rom-com and the main theme is mostly related to female leads. Both dramas have wonderful leads and a nice romance.

Both feature a female lead character that has a strong relationship that seemingly will end up in marriage. However, that is not the case. "That first relationship teaches us more about ourselves than the other person we are in the relationship with."
