FL sucks and it's okay if a character sucks but she should get some character development. I'm not saying she didn't get character development, she did, but it was sudden and it didn't make sense.
She only cared about herself and she repented at the end, when everything escalated.

She also approached ML with ulterior motives but then she fell in love with him and forgot about that. Honestly, I'm glad she did because if she asked ML to sue the guy after they were together (in love and happy), I don't think a truck of character development could make anyone like her.

The romance was cute but rushed, one moment ML is thinking of his dead wife and crying and the next he is kissing the FL.

Then they break up at some point and after that, the movie became more stupid but also more entertaining. One example, a bunch of concrete fell on ML but he is completely fine after that and running around. A bunch of concrete never fell on me but I think that's unrealistic.

Also, what was the point of FL being sick. It did nothing except make her faint at very convenient times.

Despite the garbage plot, the leads kissing and being cute together made me smile. The side characters are also nice, no one was annoying.

Overall, it's an okay movie. There's some humor and cute romance at times.
