Even If I'm a Saintess Who Isn't Loved

This act is merely for the purpose of fulfilling the marriage contract. So why does it still ache so deeply?

Mia, a commoner, was sold by her family at a young age after she developed healing magic, and was forced to work hard as a saint at the royal palace. Over the next decade, she was constantly abused by the noble saint and the second prince due to her commoner background, and eventually damaged the magical organs essential to a saint's healing magic. Upon learning this, the second prince declared, "We have no need for a 'discarded saint,'" and banished Mia from the palace.

He married her to Gilbert, nicknamed Margrave the Ripper and known for his barbaric reputation. Mia vows to keep her identity as the 'discarded saint' a secret, but Gilbert is a gentle person, contrary to the rumors, and she is relieved. However, at their wedding, Gilbert coldly tells her, "There is no love in this marriage."

A brave saint who was abandoned and a margrave who hides his true feelings slowly begin to melt each other's hearts in this obsessive, serious love fantasy.
