Probably not, but I suppose we all have our flaws. Luigi can be a bit of a doormat and somewhat emotional. But he's also very persistent, and caring, and brave when truly called to step up. Imperfect characters make for more interesting stories 🌟
Through out the games that Starlow has appeared in, I haven't seen Luigi really stand up to her once (though I could've missed something). He kinda just takes it. It seems to be something consistent about Luigi's character. Whenever people say something negative about something about him, he doesn't seem to be willing to stick up for himself. When he steps up is when people try to hurt a loved one of his. The only time I remember Luigi sticking up for himself is when Dimentio said something bad about his mustache. I guess that's the line lol.
