the usb had a presentation for one of his classes but one of his classmates stole the usb bc she was jealous of yahwi and jooin. i believe the lecturer let jooin off anyways since he's a model student but this made his classmates even more angry, ie caused him trouble. so now jooin thinks it was yahwi who stole the usb n doesnt feel like he can trust him

Another classmate (and Yahwi fan/follower) took Jooin's usb, so he didn't have his project when he was supposed to present it, causing him trouble. Since Yahwi was the one to turn it in later, Jooin is assuming that Yahwi was the one who took it to begin with to mess with him. I don't think it's been made clear how Yahwi got the usb yet. That misunderstanding was piled on top of all of the times Yahwi treated Jooin poorly, lead to Jooin confronting Yahwi like that.
I dun get why jooin is mad that yawhi returned his USB and he also mentioned “did you set up to trouble me” which us related to the USB case. So what happened there? And i think jooin misunderstood abt it but USB doesnt have to do anything with their drama does it? Someone pls explain!!!!
