Woke Up At My Own Wedding: My Wife's Recovery Makes Me Stronger

Lucius went to sleep on Earth. He woke up at his own wedding. Transported to another world on the brink of collapse, Luke suddenly finds himself married to Lady Valeria Chamberlin—the youngest SSS-Rank Mage in history and one of humanity's greatest heroes. At least, she used to be. After a mysterious Rift accident stole her hearing, her magic, and her future, Valeria was discarded by the noble family she devoted her life to protecting. Now she spends her days as a forgotten academy professor while the world slowly moves on without her. When a mysterious system awakens after their marriage, Luke discovers that every step Valeria takes toward recovery grants him power in return. As they face dangerous Rifts, academy politics, and the truth behind the accident that ruined her life, Luke finds himself determined to accomplish the impossible: Restore the fallen legend. And maybe, along the way, win her heart. — Description from novelcodex.org
