Just some feedback for the next update.
It's great that we can FINALLY customize character relations, but to really complete it, and for consistency's sake, you might want to add a tab for what the MC is to the other girls too so that that lines don't come off sounding weird when they refer to as as their (insert role).
basically: X, Y, & Z are (insert relations/roles) to MC and MC is (insert relations/role) to X, Y, & Z.
It's almost golden though.
Other than that, I'm having fun with the spa area.
