Superstar From Age 0 - Chapter 386:

“Abused and disowned by her family after she was found heavily pregnant, Ji Weixi was forced to leave her hometown with nothing to her name. She returns four years later, only to be caught in a job with Li Shaoling, her stepsister’s fiancé-to-be as her boss.

***

Ji Weixi was holding up a certain body part of the child and aiming it at the toilet.

The tot’s brow eased amidst the gushing. “”Comfy…””

Li Shaoling’s gaze was overwhelmingly icy. “”You are not allowed to touch him there!””

Ji Weixi stared at him as if she was staring at an idiot. “”By what right?””

Li Shaoling glared at her. “”You are only allowed to look at mine.””

Never!!!”

She is the slow-witted idiot of the Prime Minister’s Residence. Everyone bullies her. He is the most respected and unfeeling Prince, with frightening ability and absolute envy! Together, they are conferred an imperial edict of marriage.

Qiao Nan: Crap! I am your biological daughter, yet I am treated as if I was picked up from the streets. In fact, you treat me worse than that!

Mother Qiao: Qiao Nan, you are not as pretty or smart as your elder sister. You are not as blessed as her. You have no right to study, marry, or to have your happiness!

Qiao Nan: Why am I not allowed to study, marry, or to seek my happiness? I will find a man right now and marry him!

Qiao Nan is dumbstruck upon discovering that the man right beside her is a powerful figure in the quad—the person who has the most promising prospects to be the future Chief.

Qiao Nan stares at the well-built man in front of her. He has firm abs and cold, chilling eyes. She swallows the lump in her throat as she says her greetings, “Good Morning, Chief!”

Qin Mian opened his eyes and found himself lying in a leaky thatched room. The problem was that he was still in his family’s villa beforehand! What’s more, there was another man lying next to his leg in the quilt!

“You, you, who are you?”

The man sat up quietly, his upper body exposed as looked at Qin Mian for a moment before he carried a worn out bowl with a cracked corner from the low table at the head of the bed. The man said in a muffled voice, “Wife, drink water.”

Qin Mian’s eyes rolled backwards and he passed out.

TN:
Title explanation: 勉为其男 [miǎn wéi qí nán] have the same sound as 勉为其难 [miǎn wéi qí nán] which means to do something reluctantly. 勉 [miǎn] is also part of MC’s name: Qin Mian.  Also, 其[qí ] sounds the same as 妻 [qi] means wife. So, there are words plays. Basically, Qin Mian reluctantly becomes someone’s man [wife] after he transmigrated.
