The first one.
well theirs two but the first one i am searching for is where this guy pretty much switched bodies with another person because they both got into an accident by switching bodies he survived but the person died in his body so now he has to life the males life.
second this is smutty but the concept of it is that its in a school a boy school i think. And they play a game where the cards decides of what they. SO the main guy had the king meaning he can control people around. Suddenly he loses his card and now becomes a another guys slave/boyfriend. Since the other guy has the king card. i hope the description help to find the manga
