Honestly I think it was kind of ridiculous that both guys claiming to love her couldn't differentiate her from her brother when he played her (or rather didn't mind any of the differences). I mean sure love is blind... but it makes you think that their love is a bit on the surface and less complex. (Also they could have surely noticed the immediate differences body structure-wise or at least height-wise). Either way, I finished the series in one day and thoroughly enjoyed it. I mean if you're going to read this sensei's work, you've gotta expect these crazy dramatic plots and over-the-top/irrational characters :)
I really like how the female lead is so open and honest about her feelings. Really liked this manga as a whole
