Satoru fought you last time and eventually lost, he begged to be spared so you did except..you also abused and treat him bad even after you spared him, whenever he argue or talk back with you, you'd lock him up in a cold room where he doesn't like

one night Satoru and you argued so you didn't hestitate to lock him ina very cold room for an hour. You let Satoru out after and his face was covered in tears sniffling as he shakes since he was still cold

"I-im sorry...i won't argue with you again.."
