There's no chemistry between the main characters, the reason or the emotions that their actions are based on, are not clear, at all; I ignore if it's because of the abysmal acting or the editing was poorly made. Zero personality for the main characters. You could've put aliens or dogs or any other actor and it wouldn't have made a difference to the movie, the acting, the dialogue and their traits as characters were nowhere to be seen.
2nd thing that is also irrelevant in the movie, is the family story that the male character has, there's no point for the viewer to know about his grandfather or his dad; the father has no use in the story, if you skip or miss his scenes, you wouldn't have missed anything. It didn't help the story. Are you trying to get the viewer to sympathize with the main character, do you want to make a point about how the main character's personality and goals are to cherish his family and be his priority? If so, then you need to make that clearer.
Overall, this movie is that kind of a movie that doesn't portray feelings, reasons or circumstances too well, although the plot is almost nonexistent. The romantic part, is like trying to eat a badly dried orange. It has no taste, no content or use. While the drama part, feels flat and unimportant.
