Being a cuck has nothing to do with whether your oshi collabs with men or not. It's whether she respects her fans. If you support a vtuber who makes it clear she hates (You) and views you as an ATM then you are a cuck. It doesn't matter if she's a pure virgin or taking Tempus dick every night. If you oshi sells Daki covers to her simps and then turns around and says that she hates the kind of people who buy Daki covers and you STILL support her then you are a cuck, no questions asked.

Respect yourself and only support vtubers who respect you.
