Sub/Dom universe?!

Evangeline while reading her weekly BL manga came across a strange genre, Sub/Dom genre?.

A dom who wants to dominate, punish, and praise.

A sub needing to be dominated, punished, and praised.

A normal is someone who does not require the dynamics involved in a dom/sub relationship.

A switch can fulfill the role of either a sub or dom, depending on their partner's needs or preferences.

Interesting, she thought as she read, finding the existence of the Subs very precious, they need to be protected. She fell asleep content hoping the subs get their happy ending. Unknowingly falling into a strange world the next morning, as a man?!
