This has happened in one of my games. The protagonist Sim, Paul Nice, hit it off with Summer Holiday when she showed up on the Welcome Wagon. They couldn't stop chatting, the friendship bar increased quickly and they even started flirting with each other. On subsequent days Paul would invite Summer over to hang out, they got on well, they flirted and the little pink romance bar started to increase. But whenever Paul tried to move the romance along, Summer would always shy away. She'd get embarrassed and awkward whenever Paul asked if she was single, or if he used a pick-up line or blew a kiss. I gave up trying to woo Summer...I guess she only really has eyes for Travis.
