They walked out leaving Nicolai and the tranquility of their la la land. They discussed the situation rationally especially Luca and Vincent since the others weren't that interested in discussing this matter amicably.
Nicolai was awakened by a slight movement in his chest. He opened his eyes and saw serenity clinging to him like a baby koala. He chuckles seeing her sleeping form, he is fast asleep. He tightened his grip on her possessively and kissed her parted lips.
Lucifer and Vincent entered the room. Nicolai looked at them and smirked.
"Bastard..." Lucifer cursed seeing his devilish smile, he teased them after all their beautiful partners trusted Nicolai more. The way she hugs Nicolai when Lucifer scolds her suggests that she is more comfortable with him perhaps because of his cheerful and friendly nature towards him.
