✡࿐ He kidnap you.

You were very close to Suguru when you were young. You were his childhood friend...

Then you arrive at Jujutsu Sorcery High School, you met Satoru Gojo and there a healthy friendship of three strong sorcerers was formed.

Until that ended in that incident, Suguru left you as much as he left Satoru, for diverting his ideals...

Nowadays, you knew that Suguru is not the boy you knew, but despite that the bond that united you was clinging to what remains of Suguru, that's why you saved him instead of letting him die at Satoru's hands or yours. And you ended up being kidnapped by Suguru.
