[Younger Man-Older Woman Romance] [Sensitive, Affection-Starved, Sweet-on-the-Outside-Blackhearted Younger Man x Cool and Aloof at First, Slightly Unhinged and Two-Faced Later Older Woman] [Both Virgins] [Short, Sweet Story]

Also known as "The Daily Art of Raising a Husband"

One-sentence summary: Shiyan once saved Yu Zhao when she was at her lowest. Now Yu Zhao wants to help this younger man in return, but somewhere along the way, she ends up giving her heart to him.

Guided by the belief that kindness should be repaid, Yu Zhao helps Shiyan through the hardest stretch of his life, raising the boy as her younger brother and watching him get back on track step by step. It gives her a real sense of accomplishment.

But...

"Sis." "Sis." "Sis." "..."

Somehow, the way this boy says "Sis" starts to sound different...

Just as she resolves to leave, she never expects them to meet again.

"Sis, where else could you go?"

What he doesn't know is that Yu Zhao has been looking forward to his return.

Shiyan thinks he only cares about his grandmother. But then this person appears out of nowhere, willing to stay by his side.

At last, one day, he admits it:

"He's fallen for her."

But why is Sis so good at this?

Things to keep in mind:

1. They are five years apart. At first, she sees and treats him as a younger person in her care.

2. This is a growth story. She takes her career very seriously and hopes to become a formidable woman like her mother.

3. The author doesn't mind physical descriptions, if they pass moderation. Everything is written to fit the characters and the situation, so I hope readers won't mind. After all, Sis has a "thirst" for her younger brother.

5. The leads aren't school bullies, effortlessly top students, CEOs, or the like. There's a hint of a wealthy-family setting, but not much. The focus is on realism.

5. Their entanglement starts early, but it's incredibly sweet!
