I wonder if that was selected as a way to resolve the love triangle once Lucas realized that there's a reason romantic comedies usually make one of the members of love triangles villains, or at least don't let the audience get as close with both competers. Shows/movies that do are instead dramas, which are a completely different tone from the light-hearted romance he was going for.
Don't want to start my day off with anger at an annoying sound. Waking up me might just dismiss that instead of snoozing it in annoyance.
