Let's Break Up, My First Love Is Back

Yu Zi and Fang Jingcheng met at a freshman mixer. They were both instantly dazzled by each other and silently thought, "What the hell?" After half a month of pining and testing the waters, Yu Zi came clean first. Yu Zi: Actually, you look a lot like my unattainable crush. Fang Jingcheng: What a coincidence. You look a lot like mine, too. They exchanged a look that said they were both in the same boat, hit it off, and became stand-ins for each other's unattainable crushes. They were like tinder and flame, and their days together were happy and harmonious. Who knew that six years later, Yu Zi would ask to break up? "I'm sorry, but let's end things. The person I've always loved is back." Fang Jingcheng: ??? They'd agreed to be each other's stand-ins. Whoever fell for someone else first would be a dog. Yu Zi: For my first love, I'll gladly be a dog. Fang Jingcheng wasn't having it. He'd been with his girlfriend for six years. Was she really going to let her old flame take her away just like that?
