I definitely haven't seen a plot like this one...super interested since it delves more into attraction and sexual orientation! I think it's sweet that the female protagonist wants to keep an eye out for her younger brother, but I get the feeling that he's quite the adorable playa and Sena whose interested in her may have never found out that he's bi or pans if his new love interest hadn't disguised herself as a boy---I like that he has no trouble seducing guys...they literally fall for his Casanova ways but seducing the "plain but cute boy" really erks him! Loved this line, "I don't like you, but I like the drinks you make!"
