Oh great. The typical "I will tell you a bit of my background so that you will know why I'm doing this and feel pity towards me in order to not let you do that which you've always wanted to do with me" story. Now MC wont try to NTR his bro's waifa and instead will wholeheartedly do as she says without a second thought. Hopefully he WILL let kurebayashi sensei do him in the future...unless he is more of a stupid virgin pussy boy than we've seen so far...
