>>102718351 (OP)Don't take it too seriously. Don't dump your life savings into an oshi (or even give them a penny if you're even slightly uncomfortable with it) so if you lose interest, you won't go into a sunk-cost-fallacy urge to either defend her even if you didn't 100%-want-to, or get emotional over casual entertainment.
Watch what you want, don't let anyone try to gaslight you into liking or not liking something for whatever reason.
