After I Transmigrated into a Book, I Held My Puppy-Like Husband Close and Spoiled Him

Xi Wan transmigrated into a book! She even came with a System, but she wasn't the heroine. Instead, she became the male lead's hapless ex-girlfriend. What happens to the supporting female character? Of course, she becomes a stepping stone for the hero and heroine. The Xi and Yan families were both wealthy, powerful clans, yet the male lead brought them to ruin. Could a wealthy family really fall so easily? Xi Wan didn't believe it. The power of this plot was just too much. All she wanted was to lie flat and protect her family and that husband of hers. So how did she end up giving herself to him? She hadn't wanted that either, but he called her big sister! She couldn't resist his looks. This younger guy was just too good at this!

At first, Yan He wanted nothing more than to be alone. Marriage was merely a matter of mutual benefit.

But the way she stood up for him again and again, and comforted him time after time, completely unsettled his heart. He thought he might have fallen in love with this big sister. What was he supposed to do?

Little bonus scenes

Yan He: Big sister, did I do something wrong? Is that why you've given up on me?

Yan He: Big sister, all my fans have been won over by you. You have to make it up to me.

Yan He: Big sister, big sister.

Xi Wan: ...

Fine. With a husband like this, all she could do was spoil him.
