You're right, I read the raw and it is pretty much that.
I'd typically agree with that scenario--it's common enough; but, the way the younger expresses himself to Okuzami just doesn't mesh. Sure, we've been introduced to the idea that he's poor at expressing himself; but, at the same time, he's demonstrated that he goes to extra lengths for someone he treasures (aka the entire premise thus far), so....
I think you guys are misunderstanding the situation, older brother likes younger brother, younger brother likes okuzami. He only told him not to aproach the older brother because he thought his nii-san liked okuzami and so didn't want them to meet up. And the older brother totally knew his younger brother had a thing for okuzami so he interfered. Or at least that's my positive outlook on things. Still I'm not really into this manga, right now i guess i wanted something cute lol
