[Tw/cw; abuse/implied abuse, corporal punishment]
Whumpee who isn't aware that they're a whumpee. As in they've blocked all the memories from that time. But there's small signs such as the fact they're very people-pleasing and try to avoid conflict like the plague. Always playing the mediator role, always the first to deescalate.
One such memory being of the time they lived with two roommates; whumper and caretaker. Caretaker in the midst of being busy with their night classes isn't aware that whumper has started to inflict pain onto whumpee. They only realize when they walk into the three-bedroom apartment and witness whumper chasing whumpee with a belt raised, yelling obscenities. 'What the fuck!?' Caretaker yells at whumper, getting in the middle as to take the belt away from them.
'Really!? You're gonna stand up for that wimp, after what they've done?' The answer was an obvious yes, as they had no clue what whumper was referring to. As far as caretaker was aware, whumpee had been a model roommate. Someone they liked hanging out with. That and even if they had done someone outrageous, it couldn't have possibly warranted such a response.
Whumpee's locked themself away in their room, hyperventilating through sobs. Protesting that they hadn't done anything wrong. Once caretaker had wrangled the belt away from whumper's hands, they growled out how they'll deal with them later. The outcome in which they'd be kicked out and forced by caretaker to break the lease. Currently focused more on consoling whumpee as he couldn't stand hearing someone so distraught.
'Hey honey,' caretaker starts, voice exponentially softer than the one they had used originally with whumper. 'I don't know what's happened but I'd like to find out. Thing is we need to get your breathing under control so you don't faint. Can you let me in, sweetheart?' Acting like they were dealing with a hurt and confused kid rather than an adult.
Caretaker never gets the full story of what had happened all the times they were left alone with whumper but they get enough to know that they never want to see whumper's face again. Fearful of what they'd do.
