She really is the beautiful, bubbly, friendly type that will unintentionally draw guys like a magnet. For her the effort would be making sure to keep friendly distance instead of trying to attract a guy. (Though we all know that even an average girl who is friendly with you, talks with you, listens to you and smiles at you is already 80% of the way there.)
Lmao ' i haven't worn his clothes yet' surprised she never took the chance/opportunity if she's already sneaking her socks into his laundry? Wonder if she'd approve more of Otonashi-san tho
other than some grounded in reality seinen it seems to either be 'doting siblings on the borderline of bro/siscon' or "Super annoying sibling you wish wasn't in the story" lol
I'm surprised she's not more aware or misunderstands herself like "Are you in love with your brother? I see it a lot in anime" or something lol but would be more accurate than her interpreting enji's doujins as 'yuri' XD
