smart character(s)

Disapointed me. The MC comes back to the past from an apocaliptic futur and decides to prepare for it. His first action is ... make a lot of money?! through wall street?! I don't have anything against the fact that he might need money to buy what he needs for the futur but the wall street part is annoyingly long and is very obscure for anyone who has no economic knowlege. I did hold on for quite long hoping for it to get back on track but just gave up in the end. But the MC is indeed smart

Amazing MC reborn in an EXTREMELY evil family and destined to die at the hand of the female lead after her family kill her (the female lead's) older brother. She has to protect the guy while pretending to follow the evil family rule. The ML and her don't trust each other and her whole family is crazy but also very smart. Don't be stopped by the warning in the description, there's no NSFW content. The drawings are amazing too and the female MC is strong and smart!
