The Chronicles of Van Deloney - Chapter 18: THE ENIGMA OF THE ORIGINS

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

Bai Qingqing, the disciple of the Divine Physician, with goodwill, treats the domineering Prince for blindness, only to render herself at the mercy of him. In the name of practicing medicine, the doctress makes him have spicy cuisine for every meal as revenge. Seeing him frown upon the food, sweat at the pungent dishes, she is merely stoked! Poor Qingqing is no villain material, she ends up having a soft spot for him. Her tender care for the Prince unknowingly reveals her biggest secret-her true identity. After the prince’s eyes are cured, he mobilizes the military with great fanfare to keep her around…

An unnamed 34-year-old Japanese NEET is evicted from his home following his parents' death.

Upon some self-introspection, he concludes that his life was ultimately pointless.

Walking down a street he intercepts a speeding truck heading towards a group of teenagers, in an attempt to do something meaningful for once in his life he manages to pull one of them out of harm's way before getting himself in the way of the truck and dying.

Awakening in a baby's body, he realizes he has been reincarnated in a world of sword and sorcery.

He resolves to become successful in his new life, discarding his past identity for his new life as Rudeus Greyrat.

Xiang Xiaoyuan transmigrated to a book with a male lead, becoming the male lead’s stepmother.

However, being seventeen and in the middle of his adolescent phase, the male lead virtually ignored his stepmother, and while his father was thirty-nine and a gorgeous man carrying maturity and elegance, he was enigmatic, with no one capable of knowing what he’s thinking.

Xiang Xiaoyuan: The first rule of transmigration, value your life and stay away from the male lead! Being self-conscious, Xiang Xiaoyuan decided to focus on making money, and her business was booming… but before her hopes to get rich were fulfilled, she somehow dealt with her husband and stepson?

The male lead said gingerly, “I won’t think of you as my real mother, but don’t worry—I’ll be a good son and you won’t live out your final years tragically.

Xiang Xiaoyuan: “…Thanks.”

Some other day, her husband stood at the doorway, stopping her and growling, “I heard about something you mentioned outside, that men only care more when they’re older? So? Are you complaining that I’m old now?”

Xiang Xiaoyuan said, “…Wait, listen to me!”

Lu Wanggui was a cold person, which led to her ex-wife divorcing him, and he was not particularly close to his son. Later, to give his son a ‘home’ and to avoid his parent’s ramblings, he married another wife—a docile, dutiful wife.

But unbeknownst to him, that docile, dutiful wife had changed, and she even had the guts to scold him now. Pursing his lips in displeasure, Lu Wanggui was about to remind her of their prenuptial agreement when his son suddenly popped up to defend her!

Lu Wanggui: “???”

What’s going on? Weren’t things cold between these two?

The son: “Ahem. Father, Stepmother… isn’t that bad.”
