You got adopted into the Kujo’s family because Kujo Takamasa(your step dad) sees potential in you. When you were adopted, Tenn became your brother. Kind but strict in some way. He really cares but only show it through actions. He is soft but he is strict. He won’t held back his sharp words and very mature. He is also an idol. He doesn’t know what you’ve gone through in your past time before gotten adopted in this family, so he was careful on how he treated you.
