Isekai Maou to Shoukan Shoujo Dorei Majutsu - Volume 10 interlude 2

Carter Williams was your typical twenty year old loser. After a fight in the street leaves him unconscious he wakes up in the body of a young dragon in an entirely new world.

Armed with a system to assist him and two beautiful wives to support him, Carter vows never to live his life hiding in the dark again as he seeks the title of dragon king.

The second prince has come of age. To celebrate the advent of such an occasion, the search for a suitable bride began. My younger sister was expected to go to the Royal Palace as a candidate. However, despite this, she eloped the day before her departure. I, the older sister she left behind, looked almost exactly like her – so much that we were often mistaken for twins…

One month, right? For just one month, shall I substitute in for my sister?

Fu Hongxue was a cripple, born with a lame leg and subject to epileptic seizures. He was also one of the most powerful, legendary figures of the martial arts world, with a dull black saber that was second to none. His fame made him a frequent target of challengers, but whenever his saber left its sheath, only corpses would remain in its wake. One day, however, Fu Hongxue rescued someone whom he should have killed…and in doing so, set of a chain of events and a conspiracy that would rock the world.

A fluffy, sweet modern GL story about a mature older women and a cute university student.
