The Princess and Her Rough-Rider Khan - Chapter 651 - 649 A harmonious couple can make everything go smoothly (first update)

A 34-year-old NEET otaku, chased out from his house by his family, found that his life is reaching a dead end. He then recalled that his life could actually have been much better if he had made better choices in the past.

Just when he was at the point of regret, he saw a truck moving at fast speed, and three high schoolers in its path. Mustering all the strength he had, he tried to save them and ended getting run over by the truck, quickly ending his life.

The next time he opened his eyes, he is reincarnated to a world of sword and magic as Rudeus Greyrat. Born to a new world, a new life, Rudeus decided that, “This time, I’ll really live my life to the fullest with no regret!” Thus starts the journey of a man yearning to restart his life.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Grace Lightsinger is just a simple farm girl.Ever since the death of her parents, she's been taking this slowly, one day at a time. That changes when she dies protecting a stranger. But instead of a peaceful afterlife, she finds herself reborn as an angel with a mysterious “Saintess System” that no one else can see. She's made to choose between three factions of gorgeous immortals: warrior angels who fight demons, healer angels who tend the wounded, and love angels who raise morale through very intriguing methods.However, unlike other angels who can only master one path, Grace discovers she has an affinity for all three. This hasn't happened since the goddess Eternia herself walked the heavens, which leads to Grace learning that she might be more than just a regular angel. She might be Eternia's chosen successor, herself.But not everyone in heaven is happy about Grace's arrival. The scholarly Choir questions her legitimacy, fallen angels show dangerous interest, and that's not to even begin talking about the demons she'll be fighting.Grace wanted a peaceful afterlife, but between training, fighting demons, and trying not to die of gay panic, she's about to discover that heaven is a lot more dangerous than she ever imagined.

Perhaps the paintings in a museum are subjected to more nonsense than you would hear anywhere else in the world.The language that comes out of an artist’s life is the painting itself. It contains the most ordinary lives that know failure, desire, recoiling in fear, and compromise.Learning is about understanding that language. We miss much of what the paintings speak because there is no way to ask the long-dead painters about the philosophy of their lives.In an alleyway in the residential area of Jongno, there’s a peculiar art gallery. This place enables us to transcend such limitations. By sheer coincidence, I ended up visiting that place and began living an entirely different life.
