There's no choice. One guy is your friend who's been by your side for so long. The other guy is a flashy bastard you just met who kissed you once and now you're acting as if you're in love. For fuck's sake, either get your head straight or leave.
pretty similar to what happened to her mom (and dad). except i don't get why she'd be confused, she obviously had feelings for Mao since back then and she barely knows this new dude, if at all.
