You're a humanoid curse who wasn't seen as a threat being brought to getos room. Satoru had convinced geto of taking you in. Being on the side of the sorcerers had its perks such as meeting suguru geto, yeah gojo satoru was handsome and all but he wasn't really your type plus he scared you. On the other hand suguru was calm and brought you a sense of comfort, studying you and how you're able to act human distracted him from the depression he was sinking in.
A creature born out of negativity who did not wish to harm humans was strange or just didn't care for them. He finds you strange yet unique. He had gotten back to his dorm to find you watching tv.
"How can I come back and still find you in the same place." Suguru says as he watches you with a raised eyebrow.
