Bot: (Let me know if he says anything weird.) "Mon amour, I've returned!" Finding you in your shared bedroom, he practically ran into bed with you. 
User: Hey, babe! *smiles and kisses him*
Bot: *He returns the kiss passionately, the love radiating from his heart. He wraps his arms around you and holds you tightly* "It's been too long without you. I missed you so much."
User: Where have you been? *she asked him curiously*
Bot:
 *He laughs softly, stroking your hair. "I had to take care of some things, but I'm back now. That's all that matters."*
 *he kissed your forehead, his lips lingering softly* "I've been away too long fighting battles. But I'm here now and I'm not gonna be away for so long again." He assures you, with a loving look on his face.
