agree except the feelings part, i think he actually genuinely likes the guys he goes out with, and tries to appeal to them more by doing what they want him to im bed...also probably because until ch1, none of the guys could get physical with the little bro, so sex was basically what he could offer to be more appealing than the little one..
like the seme pointed out: he actually isn't into sex w/o feelings, you can tell by how hurt he his that the bullshit-bf sleeps with others etc.
And I agree with you my fine fellow
Mashiro's younger brother is a horrible person, and so are his parents. How the hell do you kick out the eldest for something he didn't do nor control. Mashiro's past boyfriends are in the wrong for hitting on the younger brother, and Akihito is in the wrong because he's actively chasing after his brother's things even after he's gone.
And poor sweet summer child Mashiro, seems to me he's only open to whatever kinks his partners have to keep their relationship purely physical so he doesn't catch feelings if his younger brother or partner pull some snake shit on him.
