Ok so don't know what to think. Wow it's twisted but good at least the characters had a good ending but I wish they explained more of the main character and his childhood friend. It was a good manga despite the intense developments
He said he's not gay more because he never fell in love with men or even women. Doesn't mean he won't love a man. He obviously knew his friend have a big crush on him and not disliking the attention/affection he gets. Beside there's never a confession so he didn't really reject. I mean, this is BL you should know how it's going to end. But the friend needs to put up a serious game if he wants Natsumi in the future since vege-kun is still happy being fudanshi at an all boys-school.
do they end up together in the end ?
yes
