Read my first post before reading other ones
New idea/s:
1) sung jin woo x classroom of the elite crossover - jinwoo gets teleported to cote Universe and meets ayanokoji and others. SL timeline: after jinwoo defeated the monarchs in reseted world the; cote timeline: you choose
2) sung jin woo x the system - system somehow gains mind of its own and since no one, except jinwoo, can see it, it can literally mess up with jinwoo in public, creating something like tentacles or other things and touching jinwoo, who is trying not to react when people might see him(very hard to do)
