The Frail Baby Is Carrying the Obsessive Childhood Friend's Child

*Scheming, possessive, jealous gong x cute, naive, frail straight-man shou

Pei Yanzhou and Xu Lichu grew up together as childhood friends.

Xu Lichu was born premature. He was frail and often fell ill, so his family doted on him like he was their precious darling. Pei Yanzhou also treated him like a treasure, keeping him safe in the palm of his hand and looking after him as he grew up.

Everyone knew Xu Lichu was the apple of the eldest young master of the Pei family’s eye.

After they went to the same university, Xu Lichu found himself surrounded by admirers. He had never dated anyone, and all he knew was that Pei Yanzhou didn't seem to like them.

Pei Yanzhou would tear up any love letters sent to Xu Lichu, and throw away the milk tea and snacks people gave him.

Xu Lichu would ask why, and Pei Yanzhou would tell him sternly, his face cold: "Because those people are all after Xiao Chu. They're bad people. Only your big brother truly cares about you, understand?"

Xu Lichu had always listened to Pei Yanzhou. He nodded and quietly committed it to memory.

Pei Yanzhou kept a close eye on him at school. Anyone with ulterior motives who got near Xu Lichu would be dealt with within a few days.

Sometimes, when Pei Yanzhou wasn't around, he'd make Xu Lichu report what he ate, what he did, where he went, and who he was with that day...

His controlling streak was frighteningly strong, but Xu Lichu never noticed. He thought his big brother was just looking out for him, since he'd always done so.

One time, while watching a show, Xu Lichu saw the characters kissing. He'd never tried it himself, so he asked Pei Yanzhou, "Big brother, what's it like to kiss?"

Pei Yanzhou looked at the innocent young man in front of him. He was already an adult, yet still knew nothing. Pei Yanzhou's gaze darkened. "Baby, do you want to try?"

Xu Lichu nodded honestly. By the end, his eyes were red-rimmed and brimming with tears as he hid in Pei Yanzhou's arms, gasping. "I-it's not fun. Kissing feels awful."

Pei Yanzhou gently coaxed him by the ear. "Be good. Try a few more times, and it'll start to feel nice."

Everyone around them could tell that Pei Yanzhou's feelings for Xu Lichu were unusual. One day, his roommate couldn't help asking, "Are you and Pei Yanzhou really not together?"

"Of course not! I'm straight!" Xu Lichu immediately denied it. "Pei Yanzhou is my big brother. He's just looking out for me. I'm going to date a girl."

But after class that day, his roommate saw with his own eyes Pei Yanzhou pinning Xu Lichu against a desk at the back of the classroom and kissing him until he was breathless.

"Didn't Big Brother tell Baby that you can't date anyone right now?"

Xu Lichu cried as he admitted his mistake. "Big Brother, I'm sorry. I don't want to date anyone anymore..."

At some point, in corners Xu Lichu never noticed, Pei Yanzhou's gaze had changed. It had become clinging, hungry, possessive, always fixed on Xu Lichu.

On Xu Lichu's nineteenth birthday, he got drunk and somehow ended up in bed with Pei Yanzhou. He thought it would be fine, that at most things might be awkward. Pei Yanzhou was his big brother, after all. He'd just have to pretend it was an accident. T^T

But he was wrong. After that night, Xu Lichu's body began to change in strange ways. His lower abdomen started to swell, and he was constantly nauseous and sick. When he went to the hospital for a checkup, he discovered he was pregnant!

Xu Lichu had always been a little slow, and now he was completely terrified. He ran back to the dorm in tears and showed Pei Yanzhou the test results. "Pei Yanzhou, the doctor said there's a baby in my stomach. What do I do? Am I sick? Am I going to die...?"

Pei Yanzhou looked calm, as if he had known all along. He pulled Xu Lichu into his arms and comforted him. "Of course not. Xiao Li is just pregnant."

"Don't be afraid. Big Brother will take good care of you and the baby."

[Extra 1]:

After becoming pregnant, Xu Lichu developed a skin hunger condition. He wanted to cling to Pei Yanzhou all the time, and the more he held himself back, the worse it felt. Only intimate contact could relieve it.

One night, Xu Lichu's skin hunger flared up. He sat on Pei Yanzhou's lap, crying, his eyes reddened and damp. "Big Brother, I feel awful. Help me..."

Pei Yanzhou held him by the waist. "Then lift yourself a little higher, Baby, so Big Brother can make you feel better."

[Extra 2]:

After becoming pregnant, Xu Lichu secretly replaced the vitamins and calcium tablets prescribed by the doctor with candy. When Pei Yanzhou found out, he put fluffy bunny ears and a tail on him and dressed him in a cute little skirt. "Xiao Chu did it on purpose, didn't you? You really want Big Brother to punish you, don't you?"

In the end, Xu Lichu couldn't even cry. He could only clutch his round little belly and beg softly, "Hubby, I'm sorry... I won't do it again."

[Reader advisory and content notes]:

1. The gong and shou are four years apart. One-on-one, both leads are each other's first and only, happy ending. The gong is an older, fatherly type, and the shou is a frail little cutie!

2. Same-sex marriage is legal, and the story is set at an American university. The atmosphere is open, and men with a rare special physical trait that allows them to get pregnant exist in this world.

3. The shou is a little slow. At heart, he's a silly little piglet, while the gong is a very cunning, scheming big bad wolf.

4. The main story has a long pregnancy arc, with the birth in the extra chapters. A sweet bedtime read~

5. I'll add more if I think of anything.
