Strongest Survival by Otome Game’s Heroine (LN) - Vol 4 Chapter 5: Promise

Hao Ren, an ordinary university student, saved a little girl who fell from the sky. By accident, he swallowed a “candy” that fell off of that girl’s body and somehow became the Dragon King’s son-in-law……

His life was turned upside-down from that point on.

There were dragons in this world? And they are living side-by-side with humans? Ancient Chinese Mythologies really happened?

Hao Ren got to experience a new world that was hidden from ordinary humans. Despite the thrills that came with the new discovery, there were challenges along the way.

He thought his easy life as the Dragon King’s son-in-law was going to be laid back, but conspiracies and undercurrents were coming his way.

Big news: Fu Xuechen, the great God of mathematics department, is making friends with the little cutie of the Chinese department.

Her roommate pressed her: “I heard that the great God is chasing you!!!”

Ran Xing with a blank face: “He didn’t chase me!”

Her roommate asked, “What is he looking for you?”

Ran Xing looked at the sleeping God: “Lying on the desk next to me and sleeping.”

Roommate: “…”

Fu Xuechen is a patient with severe insomnia. His dark circles are comparable to those of Gaara. He was prepared for sudden death long before he met Ran Xing.

But after one look, he fell asleep on his desk.

He simply asked for her timetable and slept next to her every day.

Later, Ran Xing rented a house outside. Her roommate asked her for something and rang the bell. But Fu Xuechen, who was only wearing pajamas, opened the door.

The roommate quickly apologized: “Sorry, I went to the wrong place.”

Fu Xuechen said lazily: “You didn’t go wrong. She’s inside!”

Roommate: “…”

She said that the great God did not chase her!!!

The more ruthless the Palace is, the more miserable the loser will end up—this he understands. But what he does not understand is, why the brother whom he lived together with peacefully in the past, would so heartlessly humiliate him today. Asking him to beg for mercy, asking him to succumb to his knees, and even… asking him to tactfully entertain him. “Yong Shan, ah, Yong Shan, as of today you are the one who qualifies to succeed as a Crown Prince, what exactly is it that you want?”

For the past 16 years, Yong Qi’s gaze was never set on him. Despite being twins with his younger brother, Yong Lin, Yong Qi has always been directing his smile and laughter towards Yong Lin, and to him, Yong Qi deliberately alienates him. He does not understand, they have the same features and looks, and he obviously is his brother too, but why won’t he be intimate with him… as if he is humiliating him. “Yong Qi, ah, Yong Qi, why won’t you understand, what I want is very simple…”
