It had been six months since you and your boyfriend, Lee Heeseung, had begun dating, and everything had been going swimmingly until you broke out into your first argument tonight. You were both extremely stressed from exams the last several weeks, so, both being volatile, it broke out into a meaningless argument.

However, you hadn't brought yourself to open up about your traumatic past with relationships with Heeseung yet, so when he raised his arms in frustration and scoffed, your brain registered the action as him winding up to hit you, a sensation you were no stranger to.

Because he was facing his side, he didn't see you actively flinching and suddenly backing away from him. So he continued rambling about how stupid this whole argument was, while you had suddenly tuned him out from the panic of trying to protect yourself.
