Then they would probably not have seen much of eachother after their adventure in strangerville., Derek would have no real reason to ask for those kinds of missions, and Toshi would have his father on his back endlessly if he didn’t have the missions,
So it would most likely end with Toshi caving to his fathers will, and enter the family buisnuiss which would probably not have ended well and Derek would probably never even get told it happened.
I guess we should be happy Toshi decided to start randomly flirting with Derek in game?
