My System Is Only Three Years Old

[A little mischief + human warmth + a hodgepodge of worldbuilding + an ensemble cast] The pacing may be slow at first, but it picks up later. Everyone is a main character. The central characters are Li Yue and Shen Ke. Everything in this story is fictional and doesn't borrow from other works. It takes a little from history, but not much.

Want to see a System and its Host bicker? Come on in. The System isn't a “real” System, but the characters are real characters. Their personalities are unpredictable. The author is too lazy to reread the earlier chapters, so a character might be serious one moment and goofing off the next.

Heroine: Li Yue

Slow to warm up, chosen by fate, not a self-sacrificing saint. She has a golden finger but barely uses it. Drawn into dreams, she repairs flaws in them and is an estranged family member of Mo Shi.

Husband: Mo Shi

After Li Yue left, he awakened memories of his past life. He has personalities from both his past and present lives, and can summon shadows. (This is relevant to the plot, but he is not a main character.)

Male lead: Shen Ke (has no romantic feelings for the heroine)

A timid little bunny, thrown into the dream by his master to help Li Yue.

The heroine's older brother in a past life. No incest.

White-bearded mouse: Hui Yu

Calls Li Yue his master. Steady and dependable, with the occasional surprising side.

Dream-devouring beast: Xiao Xing

Tsundere at first, innocent and adorable later. Cat-like, devours dreams, and loves sweet-dream fruit.

A System-like being: Peng You

Tsundere and scheming, occasionally teasing. Seems to have another identity.

Matchmaker extraordinaire: Chen Li

Can grant wishes, but at a price.

Carp spirit (villain)

Under someone's control. When not controlled, actively keeps away from their beloved.

Jing Yuan (villain)

A neighboring kingdom's prince in a past life, and a doting brother to his younger sister.

For other characters, please read the story itself. If you haven't read it, don't make assumptions. I don't accept rigid labels. There are only two main characters: the heroine takes the lead, and the male lead supports her. The story is warm, with little angst and lots of comedy.
