If You Don't Conquer Your Roommates, Will You Become a Girl?

Looking at the former roommate in front of me, I was completely lost in thought: It doesn't matter if my brother turns into a beautiful girl, no one told me that the punishment for failing the strategy is to become a beautiful girl! ! !

No, no, things shouldn't develop like this! I love it, but don't come over!
