Owari no Chronicle - Volume 13, Chapter 26: A Frank Chat About Destruction

The top student in the art exam, at the graduation ceremony, she once uttered nonsense in front of more than a thousand people: “I want to be the actor!”
– boyfriend!
Wen Yuanyu, the film star with tens of millions of girlfriend fans, looks elegant, gentle and demeanor, but when flirting, he is full of love words——
“I’ve always liked you.”
“I like you right now.”
“We’ll just go home…”
The continuous flow of sugar-coated bullets has subdued the proud and rebellious Ran Qiu into a little puppy, and even made him an underground lover.
Until one day after exercising,
The defenseless Wen Yuanyu blurted out…
The little milk dog gradually discovered that his love was full of lies, his self-esteem was wiped out, and even his career that fell to the bottom of the valley all stemmed from a deception carefully designed by Wen Yuanyu.

After deciding to break up, Ran Qiu successfully played the first male lead in his life, but Wen Yuanyu lingered, and came to co-star in this romantic movie with him.
As the movie king, Wen Yuanyu frequently NGed those scenes of physical contact, acting jerky and affectionate.
When everyone thought that the actor was interested in Ran Qiu——
But Ran Qiu raised his eyes and sneered: “For the sake of money, is your play really good enough?”

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?

PS. Cover not mine, I just found it on google.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

A continuation from where High School DxD Volume 25 left off.
