I must agree with with Sibushang and archnis. Reimu spent most of Beautiful My Dear/1 talking about how much she loved Marisa. And then she spent most of Beautiful My Dear/2 running away from her once Marisa confessed to her. It was a bit confusing and frustrating but I am glad it turned out okay in the end.
It was fun to see Suika putting up with Riemu and saving the day by giving Marisa that last push she needed.
