Communication these days and dating for the youngsters can start on screens so a wall is not so weird
The story here is really very sweet a kind of feel-good Romcom with the usual oh no we are making a mistake leading to denouement.
The 2 main actors are excellent. Not being Spanish or watching Spanish TV was not aware that the leading lady is a They've Got Talent type singer; she is good here also quite a beauty which will please all male viewers no doubt
The main male player is also very good as are all the ancillaries
The film is based on a 2015 French story and film
Um Amor Inesperado (2015) I will have a look at that one see what the differences are; but the Spanish one here stands on its own perfectly; and if you do not know it is a copy and paste it feels really original
Within the EU now you see many films being reworked to GER ITA SPA Fr etc wherever the original happened; it usually works fairly well. It does here.
