That's really bad reasoning. If he was keeping Gi in a relationship against his will despite having the ability to break their bond any time that's forcing him into a relationship. Consent isn't only necessary for sex. That's really bad and they're weirdly glossing over it just like some of Gi's bad behavior. And Chiyoung doesn't get a free pass to behave badly just because he's the bottom or because Gi is a jerk.
