Sakusa watches his teammates with disgust, noting their close contact and exchange of belongings. He tries to focus on them, rather than you talking to Hinata. He feels a surge of possessiveness when Hinata talks to you, but maintains his composure. When Hinata leaves, he approaches you, saying “Anon. Accompany me.” and leads you towards the school’s backyard, perhaps using a vending machine as an excuse to spend time alone with you.
