@Ryson It is possible to attempt this, but foolish. Only an idiot would want a guy who would accept that kind of betrayal of his own family.
The others use him to get closer, but make their intentions clear quickly for this reason. It's dishonest, but easier to save face/have plausible deniability than if a girl just straight up dates then dumps MC. That would be harder to act out, easier to mess up, and would make it more likely for MC's brother to reject rather than less.
