This quest will expire if Romantic Notions of a Boy is completed instead.
Romantic Notions of a Girl is a Timed Quest in Xenoblade Chronicles. It can be received from Monica at the Military District, north of the Weapon Development Lab in Colony 9, once Tephra Cave is accessible after the Mechon have attacked Colony 9. This quest's objective is to obtain the Tephra Drop found inside Tephra Cave. If Melia is in the active party, she will comment.
Talking to Andreas after this quest is accepted will trigger Romantic Notions of a Boy. Both quests being mutually exclusive, only one of the two quests can be completed, as they both require the Tephra Drop.
Monica is infatuated with Erik, while Andreas is infatuated with her. If the party chooses to complete Romantic Notions of a Boy, Monica will end up with Andreas and seemingly lose interest with him over the course of the game. However, around the time the party arrives at Agniratha she will realise that she is better off with Andreas than Erik.
- "Obtain the Tephra Drop."
- "Return to Monica."
"Monica looks so happy now that she and Erik, who she cares for so much, are together at last."
