In the ward, the cold boy leaned against the head of the bed, and the girl sat on the edge of the bed next to him.

One of them grabbed one side of the notebook, lowered his head, and looked at the notebook together.

One is talking, the other is listening.

"F−(M+m)gsinα=(M+m)a vs. m...... derived from Newton's second law" The girl's voice became lower and lower, and finally disappeared between her lips and teeth.

Mu Linchuan raised his head and found that the girl who was giving him a lecture couldn't open his eyelids, and a small face nodded his head like a chicken pecking rice, and finally landed on his shoulder.

Asleep?

Mu Linchuan raised his eyebrows.

Usually she falls asleep listening to lectures, and she is the first one who will fall asleep during lectures.

Mu Linchuan cautiously stretched out his hand, and at this time, the girl who was originally leaning on her shoulder sat up suddenly, and a pair of dark eyes looked at Mu Linchuan vigilantly, her eyes were full of vigilance, and it was not until she saw the young man's handsome face that the vigilance in her eyes slowly dissipated.

She seemed to have just reacted, the corners of her mouth raised slightly, and she showed a shallow smile at Mu Linchuan:

"It's you......"

"If you're sleepy, just sleep for a while." Mu Linchuan looked at the girl beside him, with a gentle light in his dark eyes.

"No, I'm not done yet! f−mgsinα=ma……”

The drowsiness still overcame Su Yi, and the eyes she forcibly opened finally couldn't hold it back, and the head on her neck shook, and finally lost her center of gravity and landed on Mu Linchuan's body.

When it fell, her lips brushed Mu Linchuan's cheeks.

Mu Linchuan's fair face was suddenly dyed red.

Her lips are so soft, so soft......

Mu Linchuan only felt that his cheeks were crisp and his heart was sweet, and that feeling lasted for a long time, and his chest seemed to be suffocated.

He turned his head, and his jade-like fingers gently brushed away her waterfall-like green silk, revealing her delicate features.

Su Yi closed his eyes, his long eyelashes were folded and curled on his eyelids, and his steady breathing fell between his neck, hot, itchy, and unbearable, a small mouth moved slightly, and the color of cherry blossoms looked so delicious.

Mu Linchuan's dark phoenix eyes narrowed into a line, staring intently at the sleeping *****.

"You kissed me first, I just exchanged courtesies."

His voice was soft, soft, so light that it was barely audible.

As he spoke, he lowered his head, and his perfect lips gently fell on the girl's cherry lips.

……

When Su Yi woke up, she found herself lying on a bed.

Where is this?

She subconsciously looked around, only to see Mu Linchuan sitting on a chair, looking down at a book, the faint white light outlined his deep and delicate facial features, making him look like a nobleman in a medieval oil painting, elegant and noble.

"Awake?" Mu Linchuan turned his head and his gentle gaze fell on her.

Su Yi's little face was crimson, she actually fell asleep in front of a boy she hadn't known for a long time, and she also occupied his hospital bed.

"I ...... I'll wash my face first......" Su Yi got out of bed in embarrassment and ran to the bathroom.

Su Yi wet his face with cold water, looked at himself in the mirror, and frowned slightly.

Since she traveled to this time and space, she has always been anxious, and she has hardly slept well, although it was only a little more than an hour just now, it was the best sleep she had!

What's going on? Is it because of him?

Calm down, calm down!

Wait a minute?

What's wrong with her lips?

Was it a mosquito bite?

Mosquitoes in 1999 really picked places, what was the wrong place to bite? How do you bite her lip?
