He basically thinks that Serina isn't good enough for his brother. He basically thinks that Serina is trashy and Isn't in love with his brother, she just likes the idea of being in love with him. Both reasons of which are misunderstandings. Really his problems with Serina are misunderstandings but do exist and aren't because "he still has that typical elementary/middle schooler boy attitude towards girls and love in general".
Maybe.
And btw, my reasoning still makes sense going by what Serina has told his brother abt the boy not getting along with other girls in the class either, but being friendly with the boys. I didn’t bring that up out of nowhere. He might have extra issues against Serina which were added to what i mentioned abt him in general.
I don’t get what his problem is with Serina. According to what Serina told Sempai abt the little bro, he doesn’t get along with other girls in the class either, but is friendly with boys.
Maybe all this negativity abt love it because he still has that typical elementary/middle schooler boy attitude towards girls and love in general. He’s never been in love or been romantically interested in anyone of the opposite sex yet. I hope we get some character development there as well.
Btw, i like how Sempai always tries to keep Serina in his mind and is always thinking about her feelings.
And i like Inoue’s reaction to the whole Serina/Higuchi thing.
