Even if the uke can't say no, THAT DOESN'T MEAN THEY HAVE CONSENTED TO HAVE SEX BY DEFAULT. The absence of no does not mean yes, get that straight. Often times, when people are getting raped, they go into shock and cannot say anything, and that's not their fault. The rapist is at fault for raping them.
When Yuuji headbutted, I thought, "Finally! an uke who can say NO(and he really accepted doing it with ONLY Kousuke) instead of giving in or being in denial about it!!!"... DANG! Also, the ending... Oh sh*t, it's gonna be baaaaad.
