Ok so it was just a bad ending @_@ i guess i picked the wrong choice... now that i remember, he said he will never hear from her again... so he wants to wait it out to get rid of all the hindrance so he can fight his yaoi love on a 1v1 fair battle @_@ and btw, we saw a CG of the girl he killed saying she loved him... he might have done it because he saw it as a betrayal to his broskie @_@ his Nii-nii won the fight and should be the one marrying her, yet she go to him and tell him she loves him instead? @_@ she might have even asked him to kill his Bro-Bro @_@ and that's why he did it @_@ not that i would forgive him for being a douche bag the whole ge @_@
