Same here. It is not easy to be in his shoes, 1st his sister like Itou and He is a man. Like I said, he is straight so hesitation and doubt about a lot of things is normal for him to feel but seems like the scanners didn't see that point. Tbh, Sempais feelings are very realistic compare to other straight characters in yaoi that I've read before.

I agree that it was cute how he was initially trying to help the little sis with her crush, but at some point he DID start bringing her up just in order to evade the issue... -_-

Again, it is normal for a straight guy to do such thing. As I said, sempai's reaction and feelings are very realistic. He's checking the reality of the situation. No straight guy will jump to a conclusion of having a relationship with same sex unless he is expose to that kind of relationship. Rather than evading the issue I see it as the right thing to do. Until the last page, I don't see Sempai as Itou's future lover, I see him as an ordinary, normal person and a loving brother, so I'm still convinced that his reactions are very normal and would not ever think that he used his sister to avoid the situation.

He did almost the same thing with the girl he liked at work, though. That's why I think there maybe something more into this? I mean, besides the sexual orientation.

Yeah maybe....but as Itou said in the below page, senpai is really a good natured person. Although, I'm guessing that his future relationship with Itou will make him realise that sometimes he needs to be selfish to be happy. He will feel possessiveness and jealousy on a different level :)

Anyways, all my comments were just based on the 2chapters. I just can't see the point that of the scanners sayin that he is an asshole. Don't get me wrong by the way I'm not saying I'm right it's just I have a different perspective on the matter like anyone else

I don't really think sexual orientation is the main issue here. I really think it's more on the issue of hesitation and doubt and he used his sister to "feel" the situation. It's like he's saying "don't immediately assume that co-worker/Itou likes you" "do they really like me?" "why me?" "there are other people who can love co-worker/Itou". But it's still just 2 chapters so... we'll see. lol.
More than anything I was really disappointed at the last page (comment).
First, what's wrong about trying to fix your sister to a good guy? Itou is a good guy, decent if I must say. I have a brother and more than anything he wants me to find a good guy and if he can choose for me, I'm pretty sure that he will choose someone like Itou, so how's that treating woman like shit?
Second, Senpai is straight from the beginning, so it's normal that instead of him he will think of his sister to partner with Itou.
The story is good because it shows how to recognize the feeling of love or attraction regardless of gender. Love is Love that's what this manga is tryin to show.
Yes, its a bit scary that senpai is still not sure what he feels but it does happen even in a heterosexual relationship; confusion, recognition, acceptance, straggles about feelings and emotions, it does happen to everyone.
