A Non-Exclusive Relationship

Peng Xuyu and Fu Shuyi are people from two different worlds. At least, that's how it looks to outsiders. At night, Fu Shuyi nestled against Peng Xuyu, rubbing against him as he watched Peng Xuyu exchange messages with someone. "Peng Xuyu, how can they say things like that about me?" he said. But Peng Xuyu didn't reply. After a long while, drowsiness finally overcame him. Fu Shuyi yawned and snuggled against Peng Xuyu before closing his eyes in peace. "Good night." Peng Xuyu looked at Fu Shuyi asleep in his arms and murmured softly to him. Peng Xuyu, why didn't you protect me? I promise you a lifetime together. Premise: Stand still and embrace the one you love
