Garon didn’t know until the MC told him just then about the bond. The MC stays with Garon at first to kill him, and then later because he’s in love with him. Raon is fine, he ends up in a small town as a sort of head figure. As to if Raon can feels the MC’s love for Garon, it’s unknown. The MC separates from Raon right after Raon names him.
From what I've read in some comments (spoiler ahead)
The brother named the MC but MC still ended up with the seme...
Did the seme know about the soul bond?
Why did MC stay with the seme and not with the brother? Was he still being threatened or did he fell in love?
What happened to the brother at the end?
If MC eventually fell in love with the seme does that mean the brother can feel his love to the seme because of the bond? That would be torture...
