among colleagues, minamo is bright and popular. i had a slight wall up against her, but at a drinking party, she came next to me and said, "let's change locations?" and we ended up having sex. she doesn't want a relationship, but wants sex, so we become sex friends. as our relationship deepens, i gradually become attracted to her, but i realize she has other sex partners besides me. i get jealous, can't forgive it, and end up forcing myself on her.
