Ch 38: this is a fun read :3 mc was called an 'oni' because of his scary appearance and strength. However one day, a girl he saved said he wasn't an oni and thanked him instead; this made him fall for her. However, to his surprise, this girl was actually an oni princess. This girl just wants a normal life, and since he is willing to do anything to make her happy, he is willing to fight any oni 'fiancees' that comes their way.
Oni mc was saved by the human ml when they were children. Years later, when the ml turned 18, the mc went back to the human world and became the ml's wife.
