I like the setup here. It clearly pulls at the heart strings. But if the child is his then supposedly there is no need to adopt. Not sure about the legal side of this. Other way to play this, is to not disclose that the daughter is his in the logline, as you can use this as the act three climax. So you could say, that he is pushed to his limit by the girl and has to decide whether he can keep his promise. Otherwise you’ve told the whole story in the logline and it should be a taster of the film. (acts 1 & 2)

I like the set up of being able to see other people’s true love. But the rest of the logline needs work. You need to find a plot that fully exploits the pros and cons of that gift. If she still believes someone was her true love and cannot get over him, that would be a good start. Her flaw maybe that she cannot see own true love and the reporter helps her see that. But you need to say that.
