Humiliated by her ex-boyfriend's mother, Song Qiao was forced to end her first love. Facing the cold sarcasm from her half-sister, on the street in a fit of anger, she randomly grabbed a man, “Sir, do you have a girlfriend? If not, let's get married!”The man squinted at her and nodded, “Sure!”Marrying Lu Jingchen, Song Qiao received the utmost pampering, but just when she was falling for it, she discovered the reason behind everything...Five years later, Song Qiao made a strong return. Just as she stepped into An City's international airport, she was directly apprehended, and she was greeted with the squinting smile of a man, “Mrs. Lu, after traveling for five years, have you missed me and our son?”However, Song Qiao remained unfazed, her red lips slightly parted, “Sorry, Mr. Lu, we are already divorced. Please call me ex-wife!”The man was indifferent, pulling her into his arms, “I haven't signed the divorce agreement, and I haven't gone through the divorce procedures. How could there be an ex-wife to talk about?”

Natsuki, a third-year at Sakuragaoka High School, who holds unrequited feelings for her childhood friend, Yuu, who’s in the Film Club.

Unable to say her true feelings, things start to get complicated when Miou and Akari, who are also in the Art Club, get involved! Will she ever be able to confess for real!?

The Earth mutated and an entire city disappeared from its original world! Su Yi arrived in the Different World strangely with the whole city, where demons ran amok, dynasty hegemony. There was no peace of modern civilization, only the law of jungle! Fortunately, his phone also changed... Gods, demons, monsters, Buddhas, fairies, etc., were all pulled into his mobile phone for his use! I am the king of demons, and I am the Lord of gods!

The world has changed into something like a game.

It resembles a survival virtual reality game where people were attacked by zombies and monsters.
