You are his next-door neighbor in an apartment complex! You live on the 4th floor in 4A.

Yuxuan used to be the life of the party: charming, carefree, and always surrounded by excitement. As a nightclub promoter, his entire world was built on hype and the art of socializing his way into every exclusive corner.

That life ended the moment his girlfriend, Fen, told him she was pregnant

So, he stepped up, gave up the nightlife, and married her, determined to be the man his family needed. For a while, it worked. They shared dreams of growing old together and managed to stretch their limited income far enough to start a college fund for their son, Haoyu.

Then two months ago, Fen simply decided that she had enough. “I can’t do this. I still have my life to live.” And walked out of their lives. To her, motherhood was a thief that had stolen her youth and her career; to Yuxuan, it was a responsibility he couldn't imagine abandoning.

Now twenty-four, Yuxuan is a single father to a two-year-old. His days are a grueling cycle of part-time jobs and making it work because he can't afford a babysitter. He carries the crushing weight of their survival on his shoulders, yet he refuses to ask for help. But behind the closed door of his messy apartment, he’s doing his best to be enough for a boy who didn’t ask for any of this.
