basically, in ch64 the tape they (bada and doha) found actually belonged to jaeseob (dark brown hair) but doha thought it was seongchan's (bada's cousin; wearing glasses). that tape had jaeseob's memory during the original start of the game (where the five of them, excluding bada, are each playing a character in a horror game) jaeseob punched seongchan because he tampered with his tape.
when doha and jaeseob were talking, jaeseob mentioned bada being an npc, who appears at the start of the game and noticed he wasn't around. doha being a crazy psychopath diverted the topic and blamed it on seongchan. hope this helps :3
