"Removal", "cut ties", it generally means the same thing when people bring this up because what they want is to have no more interactions with them, and that is tantamount to "removal" from the MC's life. But even if there was such an option to say, "I never want to see you again", that's impossible considering that Maya is Derek's sister, Josy is Tommy's half-sister, both are trying to join the HOTs and they are very closely connected to the DIKs, and the MC has classes with them. The MC would have to leave B&R to never have to see them again, so there's really no way to avoid them.
The MC is honestly being far more mature than people who have the view of wanting to completely cut all ties because whilst he may not like being rejected by them or he chooses to no longer be involved with them, he at least accepts that he'll continue to see them around college and is going to make the best of it instead of avoiding it.
